Al Viro e5a3449ce1 hostfs: fix memory handling in follow_link() ... [ Upstream commit 7f6c411c9b50cfab41cc798e003eff27608c7016 ] 1) argument should not be freed in any case - the caller already has it as ->s_fs_info (and uses it a lot afterwards) 2) allocate readlink buffer with kmalloc() - the caller has no way to tell if it's got that (on absolute symlink) or a result of kasprintf(). Sure, for SLAB and SLUB kfree() works on results of kmem_cache_alloc(), but that's not documented anywhere, might change in the future *and* is already not true for SLOB.
