Change History
v3->v4: - Extract the begin and end blocks of the rename_lock sequence number check into helper functions to make the code easier to read.
v2->v3: - Simplify prepend_name() to blindly copy the dname over until it reaches a null byte or the specified length leaving the sequence check to handle error case.
v1->v2: - Check for internal vs external dname, taking d_lock only for external dname for safety. - Replace memchr() by a byte-by-byte checking for loop. - Try lockless dentry to pathname conversion 3 times before falling back to taking the rename_lock to prevent live-lock. - Make code re-factoring suggested by George Spelvin.
