+Severity   : normal
+Frequency  : rare
+Bugzilla   : 12415
+Description: Updated patchess for new RHEL4 kernel
+Details    : Add patch ext3-unlink-race.patch
+            Updated series file ldiskfs-2.6-rhel4.series
+
+Severity   : major
+Frequency  : rare
+Bugzilla   : 6334
+Description: Multiple mount protection(MMP) support.
+Details    : This feature will protect the filesystem from being mounted more
+            than once simultaneously. It will also protect changes by e2fsprogs
+            to the filesystem if it is mounted. This assumes high importance
+            in a shared storage environment where multiple mounts can severely
+            corrupt the filesystem.

+Severity   : normal
+Bugzilla   : 10657
+Description: Add journal checksum support. (ext3 part)
+Details    : The journal checksum feature adds two new flags i.e 
+             JBD2_FEATURE_INCOMPAT_ASYNC_COMMIT and 
+            JBD2_FEATURE_COMPAT_CHECKSUM. JBD2_FEATURE_CHECKSUM flag
+            indicates that the commit block contains the checksum for
+            the blocks described by the descriptor blocks. Now commit
+            record can be sent to disk without waiting for descriptor
+            blocks to be written to disk. This behavior is controlled
+            using JBD2_FEATURE_ASYNC_COMMIT flag.
+
+Severity   : enhancement
+Bugzilla   : 10555
+Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs
+Details    : FIEMAP ioctl will allow an application to efficiently fetch the
+             extent information of a file. It can be used to map logical blocks
+             in a file to physical blocks in the block device.
