If the generic code falls back to buffered I/O on a hole XFS needs to relock, so we need to have separate functions to call unless we want to duplicate everything. The XFS patch still needs some cleaning up, but I'll try to get it in before 2.6.8. Signed-off-by:

gcc-3.4.1 errors out in 2.6.8-rc1-mm1 at arch/i386/kernel/smp.c: arch/i386/kernel/smp.c: In function `flush_tlb_others': arch/i386/kernel/smp.c:161: sorry, unimplemented: inlining failed in call to 'send_IPI_mask_bitmask': function not considered for inlining arch/i386/kernel/smp.c:9: sorry, unimplemented: called from here make[1]: *** [arch/i386/kernel/smp.o] Error 1 make: *** [arch/i386/kernel] Error 2 The <mach_ipi.h> inlines depend on functions defined further down in smp.c. Moving the #include eliminates the problem. Signed-off-by:

I find it somewhat annoying that the preprocessor expands every "inline" to "__inline__ __attribute__((always_inline)) __attribute__((always_inline))" in the current code. Fix that up. Signed-off-by:

Rationale: - if gcc 3.4 can't inline a function marked as "inline" that's a strong hint that further investigation is required - I strongly prefer a compile error over a potential runtime problem Signed-off-by:

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:
