From: Greg KH on 1 Jul 2010 14:30 2.6.32-stable review patch. If anyone has any objections, please let us know. ------------------ From: Yin Kangkai <kangkai.yin(a)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.
