gfs2: Enable rgrplvb for sb_fs_format 1802 Turn on rgrplvb by default for sb_fs_format > 1801. Mount options still have to override this so a new args field to differentiate between 'off' and 'not specified' is added, and the new default is applied only when it's not specified.

Revert "GFS2: Fix use-after-free bug on umount" This reverts commit 78802499912f1ba31ce83a94c55b5a980f250a43. The original patch is causing problems in relation to order of operations at umount in relation to jdata files. I need to fix this a different way.

GFS2: Fix remount argument parsing The following patch fixes an issue relating to remount and argument parsing. After this fix is applied, remount becomes atomic in that it either succeeds changing the mount to the new state, or it fails and leaves it in the old state. Previously it was possible for the parsing of options to fail part way though and for the fs to be left in a state where some of the new arguments had been applied, but some had not.

gfs2: Clean up freeing struct gfs2_sbd Add a free_sbd function for freeing a struct gfs2_sbd. Use that for freeing a super-block descriptor, either directly or via kobject_put.

gfs2: Add trusted xattr support Add support for an additional filesystem version (sb_fs_format = 1802). When a filesystem with the new version is mounted, the filesystem supports "trusted.*" xattrs. In addition, version 1802 filesystems implement a form of forward compatibility for xattrs: when xattrs with an unknown prefix (ea_type) are found on a version 1802 filesystem, those attributes are not shown by listxattr, and they are not accessible by getxattr, setxattr, or removexattr. This mechanism might turn out to be what we need in the future, but if not, we can always bump the filesystem version and break compatibility instead.
