Subject[PATCH v2 0/7] fuse: Some fixes for submounts
Date
v2:



- add an extra fix (patch 2) : mount is now added to the list before

unlocking sb->s_umount

- set SB_BORN just before unlocking sb->s_umount, just like it would

happen when using fc_mount() (Max)

- don't allocate a FUSE context for the submounts (Max)

- introduce a dedicated context ops for submounts

- add a extra cleanup : simplify the code even more with fc_mount()



v1:



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 (7):

fuse: Fix crash in fuse_dentry_automount() error path

fuse: Fix crash if superblock of submount gets killed early

fuse: Fix infinite loop in sget_fc()

fuse: Add dedicated filesystem context ops for submounts

fuse: Call vfs_get_tree() for submounts

fuse: Switch to fc_mount() for submounts

fuse: Make fuse_fill_super_submount() static
