2011-04-19block: Remove the extra check in queue_requests_storeTao Ma
In queue_requests_store, the code looks like if (rl->count[BLK_RW_SYNC] >= q->nr_requests) { blk_set_queue_full(q, BLK_RW_SYNC); } else if (rl->count[BLK_RW_SYNC]+1 <= q->nr_requests) { blk_clear_queue_full(q, BLK_RW_SYNC); wake_up(&rl->wait[BLK_RW_SYNC]); } If we don't satify the situation of "if", we can get that rl->count[BLK_RW_SYNC} < q->nr_quests. It is the same as rl->count[BLK_RW_SYNC]+1 <= q->nr_requests. All the "else" should satisfy the "else if" check so it isn't needed actually.

2011-04-19block: get rid of QUEUE_FLAG_REENTERJens Axboe
We are currently using this flag to check whether it's safe to call into ->request_fn(). If it is set, we punt to kblockd. But we get a lot of false positives and excessive punts to kblockd, which hurts performance. The only real abuser of this infrastructure is SCSI. So export the async queue run and convert SCSI over to use that. There's room for improvement in that SCSI need not always use the async call, but this fixes our performance issue and they can fix that up in due time.

2011-04-19perf, x86: Fix pre-defined cache-misses event for AMD family 15h cpusAndre Przywara
With AMD cpu family 15h a unit mask was introduced for the Data Cache Miss event (0x041/L1-dcache-load-misses). We need to enable bit 0 (first data cache miss or streaming store to a 64 B cache line) of this mask to proper count data cache misses. Now we set this bit for all families and models.

2011-04-18next_pidmap: fix overflow conditionLinus Torvalds
next_pidmap() just quietly accepted whatever 'last' pid that was passed in, which is not all that safe when one of the users is /proc. Admittedly the proc code should do some sanity checking on the range (and that will be the next commit), but that doesn't mean that the helper functions should just do that pidmap pointer arithmetic without checking the range of its arguments. So clamp 'last' to PID_MAX_LIMIT. The fact that we then do "last+1" doesn't really matter, the for-loop does check against the end of the pidmap array properly (it's only the actual pointer arithmetic overflow case we need to worry about, and going one bit beyond isn't going to overflow).

2011-04-18Input: xen-kbdfront - fix mouse getting stuck after save/restoreIgor Mammedov
Mouse gets "stuck" after restore of PV guest but buttons are in working condition. If driver has been configured for ABS coordinates at start it will get XENKBD_TYPE_POS events and then suddenly after restore it'll start getting XENKBD_TYPE_MOTION events, that will be dropped later and they won't get into user-space. Regression was introduced by hunk 5 and 6 of 5ea5254aa0ad269cfbd2875c973ef25ab5b5e9db ("Input: xen-kbdfront - advertise either absolute or relative coordinates").

2011-04-18GFS2: filesystem hang caused by incorrect lock orderBob Peterson
This patch fixes a deadlock in GFS2 where two processes are trying to reclaim an unlinked dinode: One holds the inode glock and calls gfs2_lookup_by_inum trying to look up the inode, which it can't, due to I_FREEING. The other has set I_FREEING from vfs and is at the beginning of gfs2_delete_inode waiting for the glock, which is held by the first. The solution is to add a new non_block parameter to the gfs2_iget function that causes it to return -ENOENT if the inode is being freed.
