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