2009-09-14fs/Kconfig: move nilfs2 outside misc filesystemsRyusuke Konishi
Some people asked me questions like the following: On Wed, 15 Jul 2009 13:11:21 +0200, Leon Woestenberg wrote: > just wondering, any reasons why NILFS2 is one of the miscellaneous > filesystems and, for example, btrfs, is not in Kconfig? Actually, nilfs is NOT a filesystem came from other operating systems, but a filesystem created purely for Linux. Nor is it a flash filesystem but that for generic block devices. So, this moves nilfs outside the misc category as I responded in LKML "Re: Why does NILFS2 hide under Miscellaneous filesystems?" (Message-Id: <20090716.002526.93465395.ryusuke@osrg.net>).

2009-09-14nilfs2: convert nilfs_bmap_lookup to an inline functionRyusuke Konishi
The nilfs_bmap_lookup() is now a wrapper function of nilfs_bmap_lookup_at_level(). This moves the nilfs_bmap_lookup() to a header file converting it to an inline function and gives an opportunity for optimization. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
2009-09-14nilfs2: allow btree code to directly call dat operationsRyusuke Konishi
The current btree code is written so that btree functions call dat operations via wrapper functions in bmap.c when they allocate, free, or modify virtual block addresses. This abstraction requires additional function calls and causes frequent call of nilfs_bmap_get_dat() function since it is used in the every wrapper function. This removes the wrapper functions and makes them available from btree.c and direct.c, which will increase the opportunity of compiler optimization.

2009-09-14nilfs2: add update functions of virtual block address to datRyusuke Konishi
This is a preparation for the successive cleanup ("nilfs2: allow btree to directly call dat operations"). This adds functions bundling a few operations to change an entry of virtual block address on the dat file. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

2009-09-14nilfs2: remove unused btree argument from btree functionsRyusuke Konishi
Even though many btree functions take a btree object as their first argument, most of them are not used in their functions. This sticky use of the btree argument is hurting code readability and giving the possibility of inefficient code generation. So, this removes the unnecessary btree arguments.

2009-09-14nilfs2: shorten freeze period due to GC in write operation v3Jiro SEKIBA
This is a re-revised patch to shorten freeze period. This version include a fix of the bug Konishi-san mentioned last time. When GC is runnning, GC moves live block to difference segments. Copying live blocks into memory is done in a transaction, however it is not necessarily to be in the transaction. This patch will get the nilfs_ioctl_move_blocks() out from transaction lock and put it before the transaction. I ran sysbench fileio test against nilfs partition. I copied some DVD/CD images and created snapshot to create live blocks before starting the benchmark. Followings are summary of rc8 and rc8 w/ the patch of per-request statistics, which is min/max and avg. I ran each test three times and bellow is average of those numers. According to this benchmark result, average time is slightly degrated. However, worstcase (max) result is significantly improved. This can address a few seconds write freeze. - random write per-request performance of rc8 min 0.843ms max 680.406ms avg 3.050ms - random write per-request performance of rc8 w/ this patch min 0.843ms -> 100.00% max 380.490ms -> 55.90% avg 3.233ms -> 106.00% - sequential write per-request performance of rc8 min 0.736ms max 774.343ms avg 2.883ms - sequential write per-request performance of rc8 w/ this patch min 0.720ms -> 97.80% max 644.280ms-> 83.20% avg 3.130ms -> 108.50% -----8<-----8<-----nilfs_cleanerd.conf-----8<-----8<----- protection_period 150 selection_policy timestamp # timestamp in ascend order nsegments_per_clean 2 cleaning_interval 2 retry_interval 60 use_mmap log_priority info -----8<-----8<-----nilfs_cleanerd.conf-----8<-----8<----- Signed-off-by: Jiro SEKIBA <jir@unicus.jp> Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

2009-09-14nilfs2: stop using periodic write_super callbackJiro SEKIBA
This removes nilfs_write_super and commit super block in nilfs internal thread, instead of periodic write_super callback. VFS layer calls ->write_super callback periodically. However, it looks like that calling back is ommited when disk I/O is busy. And when cleanerd (nilfs GC) is runnig, disk I/O tend to be busy thus nilfs superblock is not synchronized as nilfs designed. To avoid it, syncing superblock by nilfs thread instead of pdflush.

This fixes disorder of nilfs_write_super in nilfs_sync_fs.

2009-09-14nilfs2: remove redundant super block commitJiro SEKIBA
This removes redundant super block commit. nilfs_write_super will call nilfs_commit_super to store super block into block device. However, nilfs_put_super will call nilfs_commit_super right after calling nilfs_write_super. So calling nilfs_write_super in nilfs_put_super would be redundant.

2009-09-14nilfs2: always lookup disk block address before reading metadata blockRyusuke Konishi
The current metadata file code skips disk address lookup for its data block if the buffer has a mapped flag. This has a potential risk to cause read request to be performed against the stale block address that GC moved, and it may lead to meta data corruption. The mapped flag is safe if the buffer has an uptodate flag, otherwise it may prevent necessary update of disk address in the next read. This will avoid the potential problem by ensuring disk address lookup before reading metadata block even for buffers with the mapped flag.

will get rid of nilfs_get_writer() and nilfs_put_writer() pair used to retain a writable FS-instance for a period.

2009-09-08i915: disable interrupts before tearing down GEM stateLinus Torvalds
Reinette Chatre reports a frozen system (with blinking keyboard LEDs) when switching from graphics mode to the text console, or when suspending (which does the same thing). With netconsole, the oops turned out to be BUG: unable to handle kernel NULL pointer dereference at 0000000000000084 IP: [<ffffffffa03ecaab>] i915_driver_irq_handler+0x26b/0xd20 [i915] and it's due to the i915_gem.c code doing drm_irq_uninstall() after having done i915_gem_idle(). And the i915_gem_idle() path will do i915_gem_idle() -> i915_gem_cleanup_ringbuffer() -> i915_gem_cleanup_hws() -> dev_priv->hw_status_page = NULL; but if an i915 interrupt comes in after this stage, it may want to access that hw_status_page, and gets the above NULL pointer dereference. And since the NULL pointer dereference happens from within an interrupt, and with the screen still in graphics mode, the common end result is simply a silently hung machine. Fix it by simply uninstalling the irq handler before idling rather than after.
