Hi Miklós, Here's a set of patches that convert fuse to use mount API: (1) Provide a replacement for mount_bdev() that takes an fs_context to specify the parameters. I also put a block device pointer and block device file mode into the fs_context struct for use in the sget_fc() test and set functions. (2) Improve handling of fd-type parameters. (3) Convert fuse to implement the mount API interface. (4) Move as much of the subtype parameter handling into the fuse driver as possible. These are on top of: http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=mount-api-viro Thanks, David --- David Howells (4): vfs: Create fs_context-aware mount_bdev() replacement vfs: Make fs_parse() handle fs_param_is_fd-type params better fuse: Convert to mount API fuse: Move the subtype parameter into fuse fs/fs_context.c | 14 -- fs/fs_parser.c | 15 ++ fs/fuse/inode.c | 289 +++++++++++++++++++++++++------------------- fs/super.c | 111 ++++++++++++++++- include/linux/fs_context.h | 7 + 5 files changed, 291 insertions(+), 145 deletions(-)
