This set of patches includes a few dlm related fixes from Kurt, and a small, trivial cleanup by Adrian. Also included are three disk allocation patches by me - two fixes and one incremental improvement in our allocation strategy. These have been around since early June, so I think they've had enough testing that they can go upstream. Please pull from 'upstream-linus' branch of

#against V6, corrects some format problem pointed out by checkpatch.pl. For nfs exporting, ocfs2_get_dentry() returns the dentry for fh. ocfs2_get_dentry() may read from disk(when inode not in memory) without any cross cluster lock. this leads to load a stale inode. this patch fixes above problem. solution is that in case of inode is not in memory, we get the cluster lock(PR) of alloc inode

#against V6.2, add indentation. For nfs exporting, ocfs2_get_dentry() returns the dentry for fh. ocfs2_get_dentry() may read from disk(when inode not in memory) without any cross cluster lock. this leads to load a stale inode. this patch fixes above problem. solution is that in case of inode is not in memory, we get the cluster lock(PR) of alloc inode where the inode in question is allocated

changes from v4: 1, let suballoc lock covers the checking of the group. 2, add/correct some log messages. 3, use ocfs2_read_group_descriptor() instead of diry reading the group.

Linus, et al, Here are the outstanding ocfs2 fixes we have for 2.6.30. The important ones are journal credit fixes for the new indexed directories. There's also MAINTAINERS update for my ocfs2 git tree. Please pull.

changes from v3: 1, move codes that checks inode allocation bit to subfunction ocfs2_test_inode_bit(). 2, release the suballoc lock just after we get it. we should release it asap and doing so doesn't affect functionility. 3, add inode alloc slot validation.

Hi Linus, Here are some 2.6.20 fixes for ocfs2. The patch by Zhen Wei isn't really a fix, but a very small amount of support for a feature which is mostly implemented in ocfs2-tools. Considering it's just a single attribute export via configfs, I'd say it's pretty safe to merge. Please pull from 'upstream-linus' branch of

ocfs2_getattr() uses generic_fillattr() to set inode number(and other attributes). generic_fillattr() inturn fills inode number with inode->i_ino which is a 32-bit(unsigned long) value. if the ocfs2 partition is huge enough, that may become an incorrect value. the fix is filling it again after generic_fillattr() with ip_blkno(u64).

Generally, orphan scan run in ocfs2_wq and is used to replay orphan dir. So for some low end iscsi device, the delete_inode may take a long time(In some devices, I have seen that delete 500 files will take about 15 secs). This will eventually cause umount to livelock(umount has to flush ocfs2_wq which will wait until orphan scan to finish). So this patch just try to finish the orphan scan

The patch was created against a 1.4 tree. However, it applies cleanly to mainline too. The patch has been lightly tested. I am running fill_verify_holes on a non sparse volume currently. Please review. Sunil

Ocfs2 supports exporting. PROBLEM: There are 2 problems (1) Current version of ocfs2_get_dentry() may read from disk the inode WITHOUT any cross cluster lock. This may lead to load a stale inode. (2) for deleting an inode, ocfs2_remove_inode() doesn't sync/checkpoint to disk. This also may lead ocfs2_get_dentry() from other node read out stale inode. PROBLEM DETAIL: for problem (1), For
