Hi! When trying to access a large file with sshfs (on fuse), I get a kernel panic because fuse_internal_cache_attrs is asserting a write lock when it is sometimes being called from fuse_internal_do_getattr, which only asserts a read lock.
To me (i.e. someone who has never touched VFS or fuse code) this code looks wrong, and fuse_internal_do_getattr should be acquiring a write lock around its call to fuse_internal_cache_attrs, but clearly it has been working just fine for a while now as this code hasn't changed super recently so I could be missing something. Thanks, Aymeric
