2006-07-10[PATCH] tty: Remove include of screen_info.h from tty.hJon Smirl
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.

2006-07-10[PATCH] vt: Remove VT-specific declarations and definitions from tty.hJon Smirl
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.

2006-07-10[PATCH] release_firmware() fixesMagnus Damm
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.

2006-07-10[PATCH] lockdep: core, reduce per-lock class-cache sizeIngo Molnar
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.

2006-07-10[PATCH] partitions: let partitions inherit policy from diskPeter Oberparleiter
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.

2006-07-10[PATCH] reiserfs: fix journaling issue regarding fsync()Hisashi Hifumi
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.

Remove the conflict between fscontext and context mount options.

The superblock will be labeled with the label of fscontext=, thus affecting operations which check the superblock security context, such as associate permissions.

2006-07-10[PATCH] sched: fix bug in __migrate_task()Peter Williams
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().

It's useful to be able to turn off CONFIG_HOTPLUG for compile-coverage testing and for section-checking coverage.

2006-07-10[PATCH] splice: fix problems with sys_tee()Jens Axboe
Several issues noticed/fixed: - We cannot reliably block in link_pipe() while holding both input and output mutexes. So do preparatory checks before locking down both mutexes and doing the link. - The ipipe->nrbufs vs i check was bad, because we could have dropped the ipipe lock in-between. This causes us to potentially look at unknown buffers if we were racing with someone else reading this pipe. Signed-off-by: Jens Axboe <axboe@suse.de>
