18 * Initial release of ldiskfs as a separate package.
23 Description: Updated patchess for new RHEL4 kernel
24 Details : Add patch ext3-unlink-race.patch
25 Updated series file ldiskfs-2.6-rhel4.series
30 Description: Multiple mount protection(MMP) support.
31 Details : This feature will protect the filesystem from being mounted more
32 than once simultaneously. It will also protect changes by e2fsprogs
33 to the filesystem if it is mounted. This assumes high importance
34 in a shared storage environment where multiple mounts can severely
35 corrupt the filesystem.
39 Description: Add journal checksum support. (ext3 part)
40 Details : The journal checksum feature adds two new flags i.e
41 JBD2_FEATURE_INCOMPAT_ASYNC_COMMIT and
42 JBD2_FEATURE_COMPAT_CHECKSUM. JBD2_FEATURE_CHECKSUM flag
43 indicates that the commit block contains the checksum for
44 the blocks described by the descriptor blocks. Now commit
45 record can be sent to disk without waiting for descriptor
46 blocks to be written to disk. This behavior is controlled
47 using JBD2_FEATURE_ASYNC_COMMIT flag.
49 Severity : enhancement
51 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs
52 Details : FIEMAP ioctl will allow an application to efficiently fetch the
53 extent information of a file. It can be used to map logical blocks
54 in a file to physical blocks in the block device.
