[XFS] sort out opening and closing of the block devices
Currently closing the rt/log block device is done in the wrong spot, and far too early. So revampt it: - xfs_blkdev_put moved out of xfs_free_buftarg into the caller so that it is done after tearing down the buftarg completely. - call to xfs_unmountfs_close moved from xfs_mountfs into caller so that it's done after tearing down the filesystem completely. - xfs_unmountfs_close is renamed to xfs_close_devices and made static in xfs_super.c - opening of the block devices is split into a helper xfs_open_devices that is symetric in use to xfs_close_devices - xfs_unmountfs can now lose struct cred - error handling around device opening sanitized in xfs_fs_fill_super SGI-PV: 981951 SGI-Modid: xfs-linux-melb:xfs-kern:31193a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: David Chinner <dgc@sgi.com> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>
