gfs2: Flush delete work before shrinking inode cache
In gfs2_kill_sb(), flush the delete work queue after setting the
SDF_DEACTIVATING flag. This ensures that no new inodes will be
instantiated anymore, and the inode cache will be empty after the
following kill_block_super() -> generic_shutdown_super() ->
evict_inodes() call.
With that, function gfs2_make_fs_ro() now calls gfs2_flush_delete_work()
after the workqueue has been destroyed. Skip that by checking for the
presence of the SDF_DEACTIVATING flag.
