[-- Type: text/plain, Size: 18940 bytes --]
Currently we define aliases for the buffer flags in various namespaces,
which only adds confusion. Remove all but the XBF_ flags to clean this
up a bit.
Note that we still abuse XFS_B_ASYNC/XBF_ASYNC for some non-buffer uses,
but I'll clean that up later.

Remove the XFS_LOG_FORCE argument which was always set, and the XFS_LOG_URGE
define, which was never used.
Split xfs_log_force into a two helpers - xfs_log_force which forces the
whole log, and xfs_log_force_lsn which forces up to the specified LSN.
The underlying implementations already were entirely separate, as were
the users.
Also re-indent the new _xfs_log_force/_xfs_log_force which previously had
a weird coding style.
