2010-03-01Debugging options for the DMA engine subsystemLinus Walleij
This adds Kconfig options for DEBUG and VERBOSE_DEBUG to the DMA engine subsystem, I got tired of editing the Makefile manually each time I want to debug things in here, modelled this on the debug switches for other subsystems and works like a charm when working on our DMA engines.

2010-03-01ext4: Handle non empty on-disk orphan linkDmitry Monakhov
In case of truncate errors we explicitly remove inode from in-core orphan list via orphan_del(NULL, inode) without modifying the on-disk list. But later on, the same inode may be inserted in the orphan list again which will result the on-disk linked list getting corrupted. If inode i_dtime contains valid value, then skip on-disk list modification. Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2010-03-01ext4: fix error handling in migrateDmitry Monakhov
Set i_nlink to zero for temporary inode from very beginning. otherwise we may fail to start new journal handle and this inode will be unreferenced but with i_nlink == 1 Since we hold inode reference it can not be pruned. Also add missed journal_start retval check. Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2010-03-02dmaengine: shdma: convert to platform device resourcesGuennadi Liakhovetski
The shdma dmaengine driver currently uses numerous macros to support various platforms, selected by ifdef's. Convert it to use platform device resources and lists of channel descriptors to specify register locations, interrupt numbers and other system-specific configuration variants. Unavoidably, we have to simultaneously convert all shdma users to provide those resources. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Present DMA error ISR in shdma.c is bogus, it locks the system hard in multiple ways.

2010-03-01xfs: fix locking for inode cache radix tree tag updatesChristoph Hellwig
The radix-tree code requires it's users to serialize tag updates against other updates to the tree. While XFS protects tag updates against each other it does not serialize them against updates of the tree contents, which can lead to tag corruption. Fix the inode cache to always take pag_ici_lock in exclusive mode when updating radix tree tags.

2010-03-01ext4: Fix fencepost error in chosing choosing group vs file preallocation.Tao Ma
The ext4 multiblock allocator decides whether to use group or file preallocation based on the file size. When the file size reaches s_mb_stream_request (default is 16 blocks), it changes to use a file-specific preallocation. This is cool, but it has a tiny problem. See a simple script: mkfs.ext4 -b 1024 /dev/sda8 1000000 mount -t ext4 -o nodelalloc /dev/sda8 /mnt/ext4 for((i=0;i<5;i++)) do cat /mnt/4096>>/mnt/ext4/a #4096 is a file with 4096 characters. cat /mnt/4096>>/mnt/ext4/b done debuge4fs -R 'stat a' /dev/sda8|grep BLOCKS -A 1 And you get BLOCKS: (0-14):8705-8719, (15):2356, (16-19):8465-8468 So there are 3 extents, a bit strange for the lonely 15th logical block. As we write to the 16 blocks, we choose file preallocation in ext4_mb_group_or_file, but in ext4_mb_normalize_request, we meet with the 16*1024 range, so no preallocation will be carried. file b then reserves the space after '2356', so when when write 16, we start from another part. This patch just change the check in ext4_mb_group_or_file, so that for the lonely 15 we will still use group preallocation. After the patch, we will get: debuge4fs -R 'stat a' /dev/sda8|grep BLOCKS -A 1 BLOCKS: (0-15):8705-8720, (16-19):8465-8468 Looks more sane. Thanks.
