Hi Al,
Here's a set of patches that:
(1) Provides a convenience member in struct fs_context that is OR'd into
sb->s_iflags by sget_fc().
(2) Provides a convenience vfs_init_pseudo_fs_context() helper function
for doing most of the work in mounting a pseudo filesystem.
(3) Converts all the trivial filesystems that have no arguments to
fs_context.
(4) Converts binderfs (which was trivial before January).
(5) Converts ramfs, tmpfs, rootfs and devtmpfs.
(6) Kills off mount_pseudo(), mount_pseudo_xattr(), mount_ns(),
sget_userns().
The patches can be found here also:
https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git
on branch:
mount-api-viro
