Hi Al,
Here's a set of patches that converts a bunch (but not yet all!) to the new
mount API. To this end, it makes the following changes:
(1) Provides a convenience member in struct fs_context that is OR'd into
sb->s_iflags by sget_fc().
(2) Provides a convenience helper function, vfs_init_pseudo_fs_context(),
for doing most of the work in mounting a pseudo filesystem.
(3) Provides a convenience helper function, vfs_get_block_super(), for
doing the work in setting up a block-based superblock.
(4) Improves the handling of fd-type parameters.
(5) Moves some of the subtype handling int fuse.
(6) Provides a convenience helper function, vfs_get_mtd_super(), for
doing the work in setting up an MTD device-based superblock.
(7) Kills off mount_pseudo(), mount_pseudo_xattr(), mount_ns(),
sget_userns(), mount_mtd(), mount_single().
(8) Converts a slew of filesystems to use the mount API.
(9) Fixes a bug in hypfs.
The patches can be found here also:
