Not strictly needed, since we're forcing `inline' to always_inline, but it's good for documentation purposes - This function needs the always_inline otherwise you get a link error when the compile time test is not optimized away. Signed-off-by:

Attached is a cleanup of the main loops in sys_msgrcv and sys_msgsnd, based on ipc_lock_by_ptr(). Most backward gotos are gone, instead normal "for(;;)" loops until a suitable message is found. Description: - General cleanup of sys_msgrcv and sys_msgsnd: the function were too convoluted. - Enable lockless receive, update comments. - Use ipc_getref for sys_msgsnd(), it's better than rechecking that the msqid is still valid.

Independent from the other patches: undo operations should not result in out of range semaphore values. The test for newval > SEMVMX is missing. The attached patch adds the test and a comment. Signed-Off-By:

The attached patch removes sem_revalidate and replaces it with ipc_rcu_getref() calls followed by ipc_lock_by_ptr(). Signed-Off-By:
-
Manfred Spraul authored
The lifetime of the ipc objects (sem array, msg queue, shm mapping) is controlled by kern_ipc_perms->lock - a spinlock. There is no simple way to reacquire this spinlock after it was dropped to schedule()/kmalloc/copy_{to,from}_user/whatever. The attached patch adds a reference count as a preparation to get rid of sem_revalidate(). Signed-Off-By: -

The ptrace single step mode should not use the SYSGOOD bit and should not report SIGTRAP|0x80 to the ptrace parent. The following patch add an explicit check and to not add 0x80 in this is a singlestep trap. Signed-off-by:

Fixes blk_queue_resize_tags to properly handle allocation failures. Currently, if a memory allocation failure occurs during blk_queue_resize_tags, the tag map ends up getting freed, which should not happen. The old tag map should be preserved and only the resize should fail. Signed-off-by:

init_tag_map should not initialize the busy_list, refcnt, or busy fields in the tag map since blk_queue_resize_tags can call it while requests are active. Patch moves this initialization into blk_queue_init_tags. Signed-off-by:

This is a resend of three ll_rw_blk patches related to tagged queuing. Currently blk_queue_free_tags cannot be called with ops outstanding. The scsi_tcq API defined to LLD scsi drivers allows for scsi_deactivate_tcq to be called (which calls blk_queue_free_tags) with ops outstanding. Change blk_queue_free_tags to no longer free the tags, but rather just disable tagged queuing and also modify blk_queue_init_tags to handle re-enabling tagged queuing after it has been disabled.

In order for filesystems to detect asynchronous ordered write failures for buffers sent via submit_bh, they need a bit they can test for in the buffer head. This adds BH_Eopnotsupp and the related buffer operations end_buffer_write_sync is changed to avoid a printk for BH_Eoptnotsupp related failures, since the FS is responsible for a retry. sync_dirty_buffer is changed to test for BH_Eopnotsupp and return -EOPNOTSUPP to the caller Some of this came from Jens Axboe Signed-off-by:
