Change Details

vfs_cache_lookup() has already done the appropriate VEXEC check, therefore we must not re-check if we came into tmpfs_lookup1 via VOP_CACHEDLOOKUP(). This fixes O_SEARCH semantics on tmpfs and removes a redundant descent into VOP_ACCESS() in the common case. Reported-by: arichardson
