Hi all, this series is against the VFS vfs.super branch does two slightly related things: - move closing of the external devices in ext4 and xfs from ->put_super into ->kill_sb so that this isn't done under s_umount which creates lock ordere reversal - move freeing the private dta in s_fs_info into ->kill_sb for file systems that pass it in through the fs_context, as otherwise we could leak it before fill_super is called (this is something new on the vfs.super branch because of the changed place where blkdev_get is called) Changes since v1: - keep the invalidate_bdev call in XFS and actually document it - minor whitespace fixes
