Add a sanity check for the fs_info as we will dereference it, similar to what the 'store features' handler does. Signed-off-by: David Sterba <dsterba@suse.com>

The key variable occupies 17 bytes, the key_start is used once, we can simply reuse existing 'key' for that purpose. As the key is not a simple type, compiler doest not do it on itself. Signed-off-by: David Sterba <dsterba@suse.com>

The size of root item is more than 400 bytes, which is quite a lot of stack space. As we do IO from inside the subvolume ioctls, we should keep the stack usage low in case the filesystem is on top of other layers (NFS, device mapper, iscsi, etc).

When the replace target fails, the target device will be taken out of fs device list, scratch + update_dev_time and freed. However we could do the scratch + update_dev_time and free part after the device has been taken out of device list, so that we don't have to hold the device_list_mutex and uuid_mutex locks.

Austin S. Hemmelgarn authored
Currently, we don't allow the user to try and rebalance to a dup profile on a multi-device filesystem. In most cases, this is a perfectly sensible restriction as raid1 uses the same amount of space and provides better protection. However, when reshaping a multi-device filesystem down to a single device filesystem, this requires the user to convert metadata and system chunks to single profile before deleting devices, and then convert again to dup, which leaves a period of time where metadata integrity is reduced. This patch removes the single-device-only restriction from converting to dup profile to remove this potential data integrity reduction. Signed-off-by: Austin S.

Now we force to create empty block group to keep data profile alive, however, in the below example, we eventually get an empty block group while we're trying to get more space for other types (metadata/system), - Before, block group "A": size=2G, used=1.2G block group "B": size=2G, used=512M - After "btrfs balance start -dusage=50 mount_point", block group "A": size=2G, used=(1.2+0.5)G block group "C": size=2G, used=0 Since there is no data in block group C, it won't be deleted automatically and we have to get the unused 2G until the next mount. Balance itself just moves data and doesn't remove data, so it's safe to not create such a empty block group if we already have data allocated in other block groups.

The delalloc reserved space is calculated in terms of number of bytes used by an integral number of blocks. This is done by rounding down the value of 'pos' to the nearest multiple of sectorsize. The file offset value held by 'pos' variable may not be aligned to sectorsize and hence when passing it as an argument to btrfs_delalloc_release_space(), we may end up releasing larger delalloc space than we originally had reserved.

If sequential writer is writing in the middle of the page and it just redirties the last written page by continuing from it. In the above case this can end up with seeking back to that firstly redirtied page after writing all the pages at the end of file because btrfs updates mapping->writeback_index to 1 past the current one. For non-cow filesystems, the cost is only about extra seek, while for cow filesystems such as btrfs, it means unnecessary fragments. To avoid it, we just need to continue writeback from the last written page. This also updates btrfs to behave like what write_cache_pages() does, ie, bail out immediately if there is an error in writepage(). <Ref: https://www.spinics.net/lists/linux-btrfs/msg52628.html> Reported-by: Holger Hoffstätte <holger.hoffstaette@googlemail.com> Signed-off-by: Liu Bo <bo.li.liu@oracle.com> Signed-off-by: David Sterba <dsterba@suse.com>

Haswell and Broadwell can be configured to hash the channel interleave function using bits [27:12] of the physical address. On those processor models we must check to see if hashing is enabled (bit21 of the HASWELL_HASYSDEFEATURE2 register) and act accordingly.
