| |
2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------
From: Yin Kangkai <kangkai.yin@intel.com>
commit 765f8361902d015c864d5e62019b2f139452d7ef upstream.
jbd-debug and jbd2-debug is currently read-only (S_IRUGO), which is not correct. Make it writable so that we can start debuging.
