Subject: [PATCH 0/4] fuse: Some fixes for submounts

While working on adding syncfs() support in FUSE, I've hit some severe

bugs with submounts (a crash and an infinite loop). The fix for the

crash is straightforward (patch 1), but the fix for the infinite loop

is more invasive : as suggested by Miklos, a simple bug fix is applied

first (patch 2) and the final fix (patch 3) is applied on top.


Greg Kurz (4):

  fuse: Fix crash in fuse_dentry_automount() error path

  fuse: Fix infinite loop in sget_fc()

  fuse: Call vfs_get_tree() for submounts

  fuse: Make fuse_fill_super_submount() static
