[RFC PATCH 0/6] Convert mount_single-using filesystems to fs_context

Hi Al,

Here's a set of patches that convert romfs, cramfs, jffs2 and squashfs to
use the new fs_context struct and replace mount_mtd(). They have
prerequisite commits (such as replacing mount_bdev()) that can be found in
the branch detailed below.

(1) Provide a replacement for mount_mtd() that takes an fs_context to
specify the parameters.

I also put an mtd device pointer into the fs_context struct for use in
the sget_fc() test and set functions plus a destructor because
put_fs_context() can't reach into the mtd module.

(2) Convert romfs.

(3) Convert cramfs.

(4) Convert jffs2.

(5) Get rid of the now-obsolete mount_mtd() function.

(6) Convert squashfs.

These can be found in the following branch:

Thanks,
David
