When insmntque() fails, only np is released while np->n_rpath and np->n_name is leaked. The same leak occurs when vfs_hash_insert() fails. We should release the relevant memory chunk with proper function when error occurs to avoid the memory leak. --=20 You are receiving this mail because: You are the assignee for the bug.=
