In testing it was noticed that Extended Delay after Reset flag was being set for gscsi and volume set devices. This had a negative effect on performance for volume sets. The fix is to only set the flag for gscsi devices. Signed-off-by:

Before driver's own internal state is marked as PLOGI/PRLI complete. This additional check closes a window seen with dual-personality initiator/target devices where a driver's PLOGI/PRLI request occurs within the window after the target's PLOGI request has completed, but prior to the target's PRLI arriving and processed by the firmware. Without this additional check, the firmware will return port-information stating that the port neither supports target nor initiator functions, causing the driver to register the rport prematurely to the FC-transport without the proper 'roles' being set.

[SCSI] qla2xxx: Include request queue ID in the upper 16-bits of the I/O handle for Abort I/O IOCBs. The upper 16-bits of the handle for all I/O in multi-queue supported drivers carries the ID of the request queue it was submitted on. When using Abort I/O IOCB, the driver needs to also populate the upper 16-bits in the handle_to_abort field so the fw can correlate with the actual I/O. Signed-off-by:

Modifying qla24xx_get_fcp_prio() to return a 'found' status allows the driver to short circuit the 'set FCP-priority' call and reduce the amount of noise generated in the messages file: scsi(5): Unable to activate fcp priority, ret=0x102 scsi(5): Unable to activate fcp priority, ret=0x102 Also make qla24xx_get_fcp_prio() static.

The case we should be verifying when updating the dentry name is that the _parent_ inode (the directory) semaphore is held, not the semaphore for the dentry itself. It's the directory locking that rename and readdir() etc all care about. The comment just above even says so - but then the BUG_ON() still checked the dentry inode itself. Very few people noticed, because this helper function really isn't used for very much, so you had to be using ncpfs to ever hit it. I think I should just remove the BUG_ON (the function really has just one user), but let's run with it fixed for a while before getting rid of it entirely. Reported-and-tested-by:

For the explicit unplugging, we'd prefer to kick things off immediately and not pay the penalty of the latency to switch to kblockd. So let blk_finish_plug() do the run inline, while the implicit-on-schedule-out unplug will punt to kblockd. Signed-off-by:Jens Axboe <jaxboe@fusionio.com>

Christoph Hellwig authored
It's a bit of a mess currently. task->plug is being cleared and reset in __blk_finish_plug(), and blk_finish_plug() is testing for a NULL plug which cannot happen even from schedule() anymore since it uses blk_needs_flush_plug() to determine whether to call into this function at all. So get rid of some of the cruft. Signed-off-by: -

The conventional format for boolean attributes in sysfs is numeric ("0" or "1" followed by new-line). Any boolean attribute can then be read and written using a generic function. Using the strings "yes [no]", "[yes] no" (read), "yes" and "no" (write) will frustrate this.

On no-mmu arch, there is a memleak during shmem test. The cause of this memleak is ramfs_nommu_expand_for_mapping() added page refcount to 2 which makes iput() can't free that pages. The simple test file is like this: int main(void) { int i; key_t k = ftok("/etc", 42); for ( i=0; i<100; ++i) { int id = shmget(k, 10000, 0644|IPC_CREAT); if (id == -1) { printf("shmget error\n"); } if(shmctl(id, IPC_RMID, NULL ) == -1) { printf("shm rm error\n"); return -1; } } printf("run ok...\n"); return 0; } And the result: root:/> free total used free shared buffers Mem: 60320 17912 42408 0 0 -/+ buffers: 17912 42408 root:/> shmem run ok... root:/> free total used free shared buffers Mem: 60320 19096 41224 0 0 -/+ buffers: 19096 41224 root:/> shmem run ok... root:/> free total used free shared buffers Mem: 60320 20296 40024 0 0 -/+ buffers: 20296 40024 ...

Commit 1de1502c ("x86, um: now we can get rid of trivial uml headers") removed accidentally bug.h which broke UML's call tracer and bug handler. Without asm-generic/bug.h UML uses BUG() from arch/x86/ which makes use of ud2. UML cannot use ud2, it raises SIGILL in user mode. As UML has a different stack for handling signals the call trace will be cut off. Signed-off-by:
