Return to dquot.c CVS log

Up to [Development] / xfs-cmds / xfsprogs / db

New xfsprogs version - enabled unwritten extents by default, new commands
in xfs_db and xfs_admin to manipulate the version extflg bit on unmounted
filesystems, make xfs_db check for a dirty log before zeroing it in the
uuid command, man page updates, sync'd up user/kernel code and headers.
Add stripe information into xfs_bmap output.
Rationalise headers in xfs_db, fix up early initialisation so we can use
libxlog to check for a dirty log, add version command.
