      ext4: fix potential buffer head leak when add_dirent_to_buf() returns ENOSPC · 2de770a4
      Theodore Ts'o 提交于
      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.
