2005-10-30	[PATCH] Test for sb_getblk return value	Glauber de Oliveira Costa
	This patch adds tests for the return value of sb_getblk() in the ext2/3 filesystems. In fs/buffer.c it is stated that the getblk() function never fails. However, it does can return NULL in some situations due to I/O errors, which may lead us to NULL pointer dereferences Signed-off-by: Glauber de Oliveira Costa <glommer@br.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-09	[PATCH] update filesystems for new delete_inode behavior	Mark Fasheh
	Update the file systems in fs/ implementing a delete_inode() callback to call truncate_inode_pages(). One implementation note: In developing this patch I put the calls to truncate_inode_pages() at the very top of those filesystems delete_inode() callbacks in order to retain the previous behavior. I'm guessing that some of those could probably be optimized.

2005-06-24	[PATCH] xip: ext2: execute in place	Carsten Otte
	These are the ext2 related parts. Ext2 now uses the xip_* file operations along with the get_xip_page aop when mounted with -o xip. Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16	[PATCH] ext2 corruption - regression between 2.6.9 and 2.6.10	Bernard Blackham
	Whilst trying to stress test a Promise SX8 card, we stumbled across some nasty filesystem corruption in ext2. Our tests involved creating an ext2 partition, mounting, running several concurrent fsx's over it, umounting, and fsck'ing, all scripted[1]. The fsck would always return with errors. This regression was traced back to a change between 2.6.9 and 2.6.10, which moves the functionality of ext2_put_inode into ext2_clear_inode. The attached patch reverses this change, and eliminated the source of corruption. Mingming Cao <cmm@us.ibm.com> said: I think his patch for ext2 is correct. The corruption on ext3 is not the same issue he saw on ext2. I believe that's the race between discard reservation and reservation in-use that we already fixed it in 2.6.12- rc1. For the problem related to ext2, at the time when we design reservation for ext3, we decide we only need to discard the reservation at the last file close, so we have ext3_discard_reservation on iput_final- >ext3_clear_inode. The ext2 handle discard preallocation differently at that time, it discard the preallocation at each iput(), not in input_final(), so we think it's unnecessary to thrash it so frequently, and the right thing to do, as we did for ext3 reservation, discard preallocation on last iput(). So we moved the ext2_discard_preallocation from ext2_put_inode(0 to ext2_clear_inode. Since ext2 preallocation is doing pre-allocation on disk, so it is possible that at the unmount time, someone is still hold the reference of the inode, so the preallocation for a file is not discard yet, so we still mark those blocks allocated on disk, while they are not actually in the inode's block map, so fsck will catch/fix that error later. This is not a issue for ext3, as ext3 reservation(pre-allocation) is done in memory. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16	Linux-2.6.12-rc2	Linus Torvalds
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
