xfs: rename xfs_wait_buftarg() to xfs_buftarg_drain()
xfs_wait_buftarg() is vaguely named and somewhat overloaded. Its primary purpose is to reclaim all buffers from the provided buffer target LRU. In preparation to refactor xfs_wait_buftarg() into serialization and LRU draining components, rename the function and associated helpers to something more descriptive. This patch has no functional changes with the minor exception of renaming a tracepoint. Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Darrick J.
