Theodore Ts'o 2de770a406 ext4: fix potential buffer head leak when add_dirent_to_buf() returns ENOSPC ... Previously add_dirent_to_buf() did not free its passed-in buffer head in the case of ENOSPC, since in some cases the caller still needed it. However, this led to potential buffer head leaks since not all callers dealt with this correctly. Fix this by making simplifying the freeing convention; now add_dirent_to_buf() *never* frees the passed-in buffer head, and leaves that to the responsibility of its caller. This makes things cleaner and easier to prove that the code is neither leaking buffer heads or calling brelse() one time too many.
