2006-06-23[PATCH] cfq-iosched: many performance fixesJens Axboe
This is a collection of patches that greatly improve CFQ performance in some circumstances. - Change the idling logic to only kick in after a request is done and we are deciding what to do. Before the idling included the request service time, so it was hard to adjust. Now it's true think/idle time. - Take advantage of TCQ/NCQ/queueing for seeky sync workloads, but keep it in control for sync and sequential (or close to) workloads. - Expire queues immediately and move on to other busy queues, if we are not going to idle after the current one finishes. - Don't rearm idle timer if there are no busy queues. Just leave the system idle. Signed-off-by: Jens Axboe <axboe@suse.de>
2006-06-23[PATCH] cfq-iosched: correctly set ioprio on both targetsJens Axboe
Patch originally from Vasily Tarasov <vtaras@sw.ru> If you set io-priority of process 1 using sys_ioprio_set system call by another process 2 (like ionice do), then cfq_init_prio_data() function sets priority of process 2 (current) on queue of process 1 and clears the flag, that designates change of ioprio. So the process 1 will work like with priority of process 2. I propose not to call cfq_init_prio_data() on io-priority change, but only mark queue as queue with changed prority. Every time when new request comes cfq-scheduler checks for this flag and atomaticaly changes priority of queue to new value. Signed-off-by: Jens Axboe <axboe@suse.de>

2006-06-23[PATCH] Kill PF_SYNCWRITE flagJens Axboe
A process flag to indicate whether we are doing sync io is incredibly ugly. It also causes performance problems when one does a lot of async io and then proceeds to sync it. Part of the io will go out as async, and the other part as sync. This causes a disconnect between the previously submitted io and the synced io. For io schedulers such as CFQ, this will cause us lost merges and suboptimal behaviour in scheduling. Remove PF_SYNCWRITE completely from the fsync/msync paths, and let the O_DIRECT path just directly indicate that the writes are sync by using WRITE_SYNC instead.

2006-06-23[PATCH] cfq-iosched: Don't set the queue batching limitsJens Axboe

2006-06-23[PATCH] drivers/block/loop.c: don't return garbage if LOOP_SET_STATUS not calledConstantine Sapuntzakis
While writing a version of losetup, I ran into the problem that the loop device was returning total garbage. It turns out the problem was that this losetup was only issuing the LOOP_SET_FD ioctl and not issuing a subsequent LOOP_SET_STATUS ioctl. This losetup didn't have any special status to set, so it left out the call. The deeper cause is that loop_set_fd sets the transfer function to NULL, which causes no transfer to happen lo_do_transfer. This patch fixes the problem by setting transfer to transfer_none in loop_set_fd. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-06-23[PATCH] make kernel warn about incorrectly sized partitionsMike Miller
Sometimes partitions claim to be larger than the reported capacity of a disk device. This patch makes the kernel warn about those partitions. We still permit these patitions to be used. Quoting Andries Brouwer <Andries.Brouwer@cwi.nl>: Case 1: The kernel is mistaken about the size of the disk. (There are commands to clip a disk to a certain capacity, there are jumpers to tell a disk that it should report a certain capacity etc. Usually this is because of BIOS bugs. In bad cases the machine will crash in the BIOS and hence fail to boot if the disk reports full capacity.) In such cases actually accessing the blocks of the partition may work fine, or may work fine after running an unclip utility. I wrote "setmax" some years ago precisely for this reason. Case 2: There was a messy partition table (maybe just a rounding error) but the actual filesystem on the partition is contained in the physical disk. Now using the filesystem goes without problem. Case 3: Both partition and filesystem extend beyond the end of the disk. In forensic or debugging situations one often uses a copy of the start of a disk. Now access beyond the end gives an expected I/O error.

2006-06-23[PATCH] JBD: split checkpoint listsJan Kara
Split the checkpoint list of the transaction into two lists. In the first list we keep the buffers that need to be submitted for IO. In the second list are kept buffers that were already submitted and we just have to wait for the IO to complete. This should simplify a handling of checkpoint lists a bit and can eventually be also a performance gain.

2006-06-23[PATCH] When CONFIG_BASE_SMALL=1, cascade() may enter an infinite loopPorpoise
When CONFIG_BASE_SAMLL=1, cascade() in may enter the infinite loop. Because of CONFIG_BASE_SMALL=1(TVR_BITS=6 and TVN_BITS=4), the list base->tv5 may cascade into base->tv5.
