similar to: [PATCH 1/1] ocfs2: Add missing iput() during error handling in ocfs2_dentry_attach_lock()

Mainline commit a5a0a630922a2f6a774b6dac19f70cb5abd86bb0 In ocfs2_dentry_attach_lock(), if unable to get the dentry lock, we need to call iput(inode) because a failure here means no d_instantiate(), which means the normally matching iput() will not be called during dput(dentry). This patch fixes the oops that accompanies the following message: (3996,1):dlm_empty_lockres:2708 ERROR: lockres

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.

In commit ea455f8ab68338ba69f5d3362b342c115bea8e13, we move the dentry lock put process into ocfs2_wq. This is OK for most case, but as for umount, it lead to at least 2 bugs. See http://oss.oracle.com/bugzilla/show_bug.cgi?id=1133 and http://oss.oracle.com/bugzilla/show_bug.cgi?id=1135. And it happens easily if we have opened a lot of inodes. For 1135, the reason is that during umount will call

The return value of btrfs_lookup_dentry is checked so that the panic such as illegal address reference should not occur.

Clean up btrfs_lookup_dentry() to never return NULL, but PTR_ERR(-ENOENT) instead. This keeps the return value convention consistent. Callers who use btrfs_lookup_dentry() require a trivial update. create_snapshot() in particular looks like it can also lose a BUG_ON(!inode) which is not really needed - there seems less harm in returning ENOENT to userspace at that point in the stack than there

A change was made to ext3 in 2.4.20-pre9 which will cause the filesystem to run ext3_mark_inode_dirty() against a freed inode. This will occur when an application attempts to add a new file/directory to the filesystem and encounters space or inode exhaustion. The results of this are unpredictable. Usually, nothing happens. But it can cause random memory corruption on SMP, and the kernel will

Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

Hi! Seems we're facing some memory leak here. This is vanilla 2.6.19-rc6 on a x86_64 box, 4GB RAM. A simple `ls -Rn' on a filesystem with lots of files makes the box leak so much RAM that the OOM killer starts to kick in. With slab alloc debugging turned on, we see this: # mount; ls -Rn; wait some seconds; Ctrl-C [root@lnxp-1038:/backend1]$ cat /proc/slab_allocators | egrep
