From jin.dongming@np.css.fujitsu.com Mon Sep 14 13:17:53 2009 From: Jin Dongming Date: Mon, 14 Sep 2009 16:02:26 +0900 Subject: mem_class: fix bug To: Jiri Kosina , gregkh Cc: Kenji Kaneshige , Hidetoshi Seto Message-ID: <4AADEA82.8000500@np.css.fujitsu.com> When I build and boot -next on fedora 10, I can not login anymore. When I input the user name and password, the system does not output any message and requires user to input the user name and password again and again. I find the patch which caused this problem with "GIT BISECT" command. And the patch is commit 7c4b7daa1878972ed0137c95f23569124bd6e2b1 "mem_class: use minor as index instead of searching the array". Though I don't know the real reason why user could not login, I confirmed the patch I made as following could resolve the problem on fedora 10.
