From: Jiri Kosina Date: Mon, 16 Jul 2007 06:41:51 +0000 (-0700) Subject: kernel/printk.c: document possible deadlock against scheduler X-Git-Tag: v2.6.23-rc1~803 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1492192b4a0bb84dd9b792cc0bd30583220a28a7;p=pandora-kernel.git kernel/printk.c: document possible deadlock against scheduler kernel/printk.c: document possible deadlock against scheduler The printk's comment states that it can be called from every context, which might lead to false illusion that it could be called from everywhere without any restrictions. This is however not true - a call to printk() could deadlock if called from scheduler code (namely from schedule(), wake_up(), etc) on runqueue lock when it tries to wake up klogd. Document this.
