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