If we failed to actually allocate the correct size of the extent to relocate we will end up in an infinite loop because we won't return an error, we'll just move on to the next extent. So fix this up by returning an error, and then fix all the callers to return an error up the stack rather than BUG_ON()'ing. Thanks, Signed-off-by:

Pull SCSI fix from James Bottomley: "This is a bug fix for the pm80xx driver. It turns out that when the new hardware support was added in 3.10 the IO command size was kept at the old hard coded value. This means that the driver attaches to some new cards and then simply hangs the system" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: [SCSI] pm80xx: fix Adaptec 71605H hang

When the binary search returns 0 (exact match), the target key will necessarily be at slot 0 of all nodes below the current one, so in this case the binary search is not needed because it will always return 0, and we waste time doing it, holding node locks for longer than necessary, etc. Below follow histograms with the times spent on the current approach of doing a binary search when the previous binary search returned 0, and times for the new approach, which directly picks the first item/child node in the leaf/node.

We only need an async starter if we can't make a GFP_NOFS allocation in our current path. This is the case for the endio stuff since it happens in IRQ context, but things like the caching thread workers and the delalloc flushers we can easily make this allocation and start threads right away. Also change the worker count for the caching thread pool. Traditionally we limited this to 2 since we took read locks while caching, but nowadays we do this lockless so there's no reason to limit the number of caching threads. Thanks, Signed-off-by:

This fixes a problem where if we fail a truncate we will leave the i_size set where we wanted to truncate to instead of where we were able to truncate to. Fix this by making btrfs_truncate_inode_items do the disk_i_size update as it removes extents, that way it will always be consistent with where its extents are. Then if the truncate fails at all we can update the in-ram i_size with what we have on disk and delete the orphan item. Thanks, Signed-off-by:

If there's an ongoing transaction when the uuid scan kthread attempts to create one, the kthread will block, waiting for that transaction to finish while it's keeping locks on the tree root, and in turn the existing transaction is waiting for those locks to be free.

AFAICT chunk 0 is no longer special, and so it should be restriped just like every other chunk. One reason for this change is us refusing the relocation can lead to filesystems that can only be mounted ro, and never rw -- see the bugzilla [1] for details. The other reason is that device removal code is already doing this: it will happily relocate chunk 0 is part of shrinking the device. [1] https://bugzilla.kernel.org/show_bug.cgi?id=60594Reported-by:

We currently have this problem where you can truncate pages that have not yet been written for an ordered extent. We do this because the truncate will be coming behind to clean us up anyway so what's the harm right? Well if truncate fails for whatever reason we leave an orphan item around for the file to be cleaned up later. But if the user goes and truncates up the file and tries to read from the area that had been discarded previously they will get a csum error because we never actually wrote that data out. This patch fixes this by allowing us to either discard the ordered extent completely, by which I mean we just free up the space we had allocated and not add the file extent, or adjust the length of the file extent we write. We do this by setting the length we truncated down to in the ordered extent, and then we set the file extent length and ram bytes to this length. The total disk space stays unchanged since we may be compressed and we can't just chop off the disk space, but at least this way the file extent only points to the valid data. Then when the file extent is free'd the extent and csums will be freed normally. This patch is needed for the next series which will give us more graceful recovery of failed truncates.

One of the complaints we get a lot is how many BUG_ON()'s we have. So to help with this I'm introducing a kconfig option to enable/disable a new ASSERT() mechanism much like what XFS does. This will allow us developers to still get our nice panics but allow users/distros to compile them out. With this we can go through and convert any BUG_ON()'s that we have to catch actual programming mistakes to the new ASSERT() and then fix everybody else to return errors. This will also allow developers to leave sanity checks in their new code to make sure we don't trip over problems while testing stuff and vetting new features. Thanks, Signed-off-by:

I noticed that if I tried to mount a file system with -o degraded after having done it once already we would fail to mount. This is because the fs_devices->missing count was getting bumped everytime we mounted, but not getting reset whenever we unmounted.

Mitch Harder noticed that the patch 3c64a1ab mentioned in the subject line was causing a kernel BUG() on snapshot deletion. The patch was wrong. It did not handle cached roots correctly. The check for root_refs == 0 was removed everywhere where btrfs_read_fs_root_no_name() had been used to retrieve the root, because this check was already dealt with in btrfs_read_fs_root_no_name(). But in the case when the root was found in the cache, there was no such check. This patch adds the missing check in the case where the root is found in the cache. Reported-by:

The handler for the ioctl BTRFS_IOC_FS_INFO was reading the number of devices before acquiring the device list mutex. This could lead to inconsistent results because the update of the device list and the number of devices counter (amongst other counters related to the device list) are updated in volumes.c while holding the device list mutex - except for 2 places, one was volumes.c:btrfs_prepare_sprout() and the other was volumes.c:device_list_add(). For example, if we have 2 devices, with IDs 1 and 2 and then add a new device, with ID 3, and while adding the device is in progress an BTRFS_IOC_FS_INFO ioctl arrives, it could return a number of devices of 2 and a max dev id of 3. This would be incorrect. Also, this ioctl handler was reading the fsid while it can be updated concurrently. This can happen when while a new device is being added and the current filesystem is in seeding mode. Example: $ mkfs.btrfs -f /dev/sdb1 $ mkfs.btrfs -f /dev/sdb2 $ btrfstune -S 1 /dev/sdb1 $ mount /dev/sdb1 /mnt/test $ btrfs device add /dev/sdb2 /mnt/test If during the last step a BTRFS_IOC_FS_INFO ioctl was requested, it could read an fsid that was never valid (some bits part of the old fsid and others part of the new fsid). Also, it could read a number of devices that doesn't match the number of devices in the list and the max device id, as explained before. Signed-off-by:

This change fixes an issue when removing a device and writing all super blocks run simultaneously. Here's the steps necessary for the issue to happen: 1) disk-io.c:write_all_supers() gets a number of N devices from the super_copy, so it will not panic if it fails to write super blocks for N - 1 devices; 2) Then it tries to acquire the device_list_mutex, but blocks because volumes.c:btrfs_rm_device() got it first; 3) btrfs_rm_device() removes the device from the list, then unlocks the mutex and after the unlock it updates the number of devices in super_copy to N - 1. 4) write_all_supers() finally acquires the mutex, iterates over all the devices in the list and gets N - 1 errors, that is, it failed to write super blocks to all the devices; 5) Because write_all_supers() thinks there are a total of N devices, it considers N - 1 errors to be ok, and therefore won't panic. So this change just makes sure that write_all_supers() reads the number of devices from super_copy after it acquires the device_list_mutex. Conversely, it changes btrfs_rm_device() to update the number of devices in super_copy before it releases the device list mutex. The code path to add a new device (volumes.c:btrfs_init_new_device), already has the right behaviour: it updates the number of devices in super_copy while holding the device_list_mutex. The only code path that doesn't lock the device list mutex before updating the number of devices in the super copy is disk-io.c:next_root_backup(), called by open_ctree() during mount time where concurrency issues can't happen.

A user was reporting weird warnings from btrfs_put_delayed_ref() and I noticed that we were doing this list_del_init() on our head ref outside of delayed_refs->lock. This is a problem if we have people still on the list, we could end up modifying old pointers and such. Fix this by removing us from the list before we do our run_delayed_ref on our head ref.

We were unconditionally clearing our runtime flag on the inode on error when trying to insert an orphan item. This is wrong in the case of -EEXIST since we obviously have an orphan item. This was causing us to not do the correct cleanup of our orphan items which caused issues on cleanup. This happens because currently when truncate fails we just leave the orphan item on there so it can be cleaned up, so if we go to remove the file later we will hit this issue. What we do for truncate isn't right either, but we shouldn't screw this sort of thing up on error either, so fix this and then I'll fix truncate in a different patch. Thanks, Signed-off-by:

The internal btrfs device id is a u64, hence make the constant BTRFS_DEV_REPLACE_DEVID "unsigned long long" as well, so we no longer need a cast to print it. Signed-off-by:
