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