When an array is started we start one or two threads (two if there is a reshape or recovery that needs to be completed). We currently start these *before* the array is completely set up and in particular before queue->queuedata is set. If the thread actually starts very quickly on another CPU, we can end up dereferencing queue->queuedata and oops. This patch also makes sure we don't try to start a recovery if a reshape is being restarted. Signed-off-by:

This has to be done in ->load_super, not ->validate_super Without this, hot-adding devices to an array doesn't always work right - though there is a work around in mdadm-2.5.2 to make this less of an issue. Signed-off-by:

I have reports of a problem with raid5 which turns out to be because the raid5 device gets stuck in a 'plugged' state. This shouldn't be able to happen as 3msec after it gets plugged it should get unplugged. However it happens none-the-less. This patch fixes the problem and is a reasonable thing to do, though it might hurt performance slightly in some cases. Until I can find the real problem, we should probably have this workaround in place. Signed-off-by:

screen_info.h doesn't have anything to do with the tty layer and shouldn't be included by tty.h. This patches removes the include and modifies all users to directly include screen_info.h. struct screen_info is mainly used to communicate with the console drivers in drivers/video/console. Note that this patch touches every arch and I have no way of testing it. If there is a mistake the worst thing that will happen is a compile error.

MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h allows all of the framebuffer and VT console drivers to remove their dependency on tty.h. [akpm@osdl.org: fix alpha build] Signed-off-by:

Use release_firmware() to free requested resources. According to Documentation/firmware_class/README the request_firmware() call should be followed by a release_firmware(). Some drivers do not however free the firmware previously allocated with request_firmware(). This patch tries to fix this by making sure that release_firmware() is used as expected. Signed-off-by:

As I was looking over the get_sb() changes, I stumbled across a little mistake in the documentation updates. Unless we're getting into an interesting new object-oriented realm, I doubt that get_sb() should really return "struct int"... Signed-off-by:

lockdep_map is embedded into every lock, which blows up data structure sizes all around the kernel. Reduce the class-cache to be for the default class only - that is used in 99.9% of the cases and even if we dont have a class cached, the lookup in the class-hash is lockless. This change reduces the per-lock dep_map overhead by 56 bytes on 64-bit platforms and by 28 bytes on 32-bit platforms. Signed-off-by:

Change the partition code in fs/partitions/check.c to initialize a newly detected partition's policy field with that of the containing block device (see patch below). My reasoning is that function set_disk_ro() in block/genhd.c modifies the policy field (read-only indicator) of a disk and all contained partitions. When a partition is detected after the call to set_disk_ro(), the policy field of this partition will currently not inherit the disk's policy field. This behavior poses a problem in cases where a block device can be 'logically de- and reactivated' like e.g. the s390 DASD driver because partition detection may run after the policy field has been modified.

* Document the ip command a little differently to make the interaction between defaults and autoconfiguration a little clearer (I hope) * Update autoconfiguration the current set of options, including DHCP * Update the boot methods to add syslinux and isolinux, and remove dd of=/dev/fd0 which is no longer supported by linux * Add a referance to initramfs along side initrd. Should the latter and its document be removed some time soon? * Various cleanups to put the text consistently into the thrid person * Reformated a bit to fit into 80 columns a bit more nicely * Should the bootloaders documentation be removed or split into a separate documentation, it seems somewhat out of scope Signed-off-by:

When write() extends a file(i_size is increased) and fsync() is called, change of inode must be written to journaling area through fsync(). But,currently the i_trans_id is not correctly updated when i_size is increased. So fsync() does not kick the journal writer. Reiserfs_file_write() already updates the transaction when blocks are allocated, but the case when i_size increases and new blocks are not added is not correctly treated. Following patch fix this bug. Signed-off-by:

Remove the conflict between fscontext and context mount options. If context= is specified without fscontext it will operate just as before, if both are specified we will use mount point labeling and all inodes will get the label specified by context=. The superblock will be labeled with the label of fscontext=, thus affecting operations which check the superblock security context, such as associate permissions. Signed-off-by:

Problem: In the function __migrate_task(), deactivate_task() followed by activate_task() is used to move the task from one run queue to another. This has two undesirable effects: 1. The task's priority is recalculated. (Nowhere else in the scheduler code is the priority recalculated for a change of CPU.) 2. The task's time stamp is set to the current time. At the very least, this makes the adjustment of the time stamp before the call to deactivate_task() redundant but I believe the problem is more serious as the time stamp now holds the time of the queue change instead of the time at which the task was woken. In addition, unless dest_rq is the same queue as "current" is on the time stamp could be inaccurate due to inter CPU drift. Solution: Replace the call to activate_task() with one to __activate_task(). Signed-off-by:

It's useful to be able to turn off CONFIG_HOTPLUG for compile-coverage testing and for section-checking coverage. But a few things go and select CONFIG_HOTPLUG, making it a royal PITA to turn the thing off. It's only turnable offable if CONFIG_EMBEDDED anyway. So let's make those things depend on HOTPLUG, not select it. Cc: Greg KH <greg@kroah.com> Cc: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by:

Use "+m" rather than a combination of "=m" and "m" for improved clarity and consistency. This also fixes some inlines that incorrectly didn't tell the compiler that they read the old value at all, potentially causing the compiler to generate bogus code. It appear that all of those potential bugs were hidden by the use of extra "volatile" specifiers on the data structures in question, though. Signed-off-by: -
