similar to: [PATCH] IGET: Remove initialisation of read_inode() super op from BTRFS

This patch fixes the data loss which can occur when unmounting a data=journal ext3 filesystem. The core problem is that the VFS doesn't tell the filesystem enough about what is happening. ext3 _needs_ to know the difference between regular memory-cleansing writeback and sync-for-data-integrity purposes. (These two operations are really quite distinct, and the kernel has got it wrong for

Hello Andrew, I patched 2.4.20 with your patch found out on http://lwn.net/Articles/17447/ and I have a big problem with: once server is booted on 2.4.20 with your patch, when I want to reboot with /sbin/reboot, server makes a Segmentation fault and it crashs. I tested it on 50-60 servers and it is the same problem. I tested kernel 2.4.20 without your patch: no problem. # uname -a Linux XXXXXX

hello, Chris In the next several months, I will have a lot of spare time. I will be happy if you assign some work to me. I have learn linux kernel for years but only fix a few small bugs in IP stack. In the past few months, I read some EXT4/VFS codes. I began reading source of btrfs ten days ago and have read it twice now. Regards YZ

Hi Chris. I think it is needed to call mark_inode_dirty() when file size expands in order to flush metadata updates to HDD through sync() syscall or background_writeout(). Thanks.

Hi, Here''s an implementation of NFS support for btrfs. It does not work in one particular case as described in http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg00298.html. This uses the btrfs_iget helper introduced previously. Comments ? --- Signed-off-by: Balaji Rao <balajirrao@gmail.com> diff -r 3f0eee804974 Makefile --- a/Makefile Thu Jun 26 10:34:20 2008 -0400

This patch finally gives us full proper -ENOSPC handling for btrfs. Now whenever you do a btrfs_start_transaction, you must specify the number of items you are planning to add/delete/modify. The worst case number of blocks that could be modified by changing that number of items will be calculated and checked against the amount of free space in the space_info where the root you are modifying

Hi, This is the second batch of Ocfs2 patches intended for the merge window. The 1st batch were sent out previously: http://lkml.org/lkml/2008/12/19/280 The bulk of this set is comprised of Jan Kara's patches to add quota support to Ocfs2. Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have
