Public bug reported: Trying to create a symlink in a filesystem mounted by fuseext2 causes the fuseext2 userspace process to deadlock before responding to the fuse request. This is simply due to a code bug in fuse-ext2/op_link.c (lines 104 and 109) where the code calls FUSE_EXT2_LOCK rather than FUSE_EXT2_UNLOCK on exiting the function.
I've confirmed that making that changes allows me to create symlinks happily on the mounted filesystem. The bug appears to exist upstream too.
