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.
