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

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.
