From b87324d082d9d898e3c06b2a07a2b94b2430b8ba Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Tue, 7 Jul 2009 10:32:58 +0100 Subject: [PATCH] kmemleak: Do not acquire scan_mutex in kmemleak_open() Initially, the scan_mutex was acquired in kmemleak_open() and released in kmemleak_release() (corresponding to /sys/kernel/debug/kmemleak operations). This was causing some lockdep reports when the file was closed from a different task than the one opening it. This patch moves the scan_mutex acquiring in kmemleak_write() or kmemleak_seq_start() with releasing in kmemleak_seq_stop(). Signed-off-by: Catalin Marinas --- Reading git-format-patch failed
