6 Description: migrate ldiskfs - ldiskfs2 (extents on directories)
7 Details : disable preallocation for non-regular files.

16 Description: Kernel BUG at ... ldiskfs/ldiskfs/mballoc.c:3853
17 Details : Removing the underlying device (e.g. via a SCSI rescan) can cause a
18 kernel BUG in ldiskfs_mb_discard_inode_preallocations().
22 Description: deadlock in ext3_expand_extra_isize
23 Details : Inode expansion during ext3_mark_inode_dirty may lead to deadlock.
24 This is solved by making sure that ext3_expand_extra_isize isn't
25 called from ext3_xattr_set_handle.
29 Description: soft lockups on 1.6.2 MDS (is_subdir)
30 Details : don't add dentries with ".." to dcache and ignore such dentries in
34 Frequency : very rare, if additional xattrs are used on kernels >= 2.6.12
36 Description: files may lose file attributes in some cases
37 Details : If there are multiple extended attributes stored on the inode,
38 in particular ACLs, SELinux, or user attributes (if user_xattr
39 is specified for the client mount options) then there is a risk
40 of attribute loss. If an additional attribute is be stored
41 initially in the inode and then increase in size enough to be
42 moved to the external attribute block (e.g. ACL growing in size)
43 for the attribute to be lost.

52 Description: Add support for vanilla-2.6.22 kernel.

61 Description: statfs speedup patches.
62 Details : The patches improve statfs performance for very large
66 Frequency : if the uninit_groups feature is enabled on ldiskfs
68 Description: e2fsck reports "invalid unused inodes count"
69 Details : If a new ldiskfs filesystem is created with the "uninit_groups"
70 feature and only a single inode is created in a group then the
71 "bg_unused_inodes" count is incorrectly updated. Creating a
72 second inode in that group would update it correctly.

76 2007-09-27 Cluster File Systems, Inc. <info@clusterfs.com>
79 Severity : enhancement
81 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs
82 Details : FIEMAP ioctl will allow an application to efficiently fetch the
83 extent information of a file. It can be used to map logical blocks
84 in a file to physical blocks in the block device.
86 --------------------------------------------------------------------------------
88 2007-08-29 Cluster File Systems, Inc. <info@clusterfs.com>
94 Description: Multiple mount protection(MMP) support.
95 Details : This feature will protect the filesystem from being mounted more
96 than once simultaneously. It will also protect changes by e2fsprogs
97 to the filesystem if it is mounted. This assumes high importance
98 in a shared storage environment where multiple mounts can severely
99 corrupt the filesystem.

105 * Initial release of ldiskfs as a separate package.
110 Description: Updated patchess for new RHEL4 kernel
111 Details : Add patch ext3-unlink-race.patch
