Re: [PATCH RT 2/2] fix printk flush of messages

[Frank Rowand]

The patches were tested on an ARM panda board for linux-3.4-rc5-rt6.

The panda board has a compile error in linux-3.4-rc5, which is fixed
by commit 13176a89e1c4a0011bd9f576730b0338ecb619ff in linux-3.4-rc6.

Without the patch, the printk() output from the following commands
does not appear on the console, until flushed by 'echo >/dev/console'

   echo h >/proc/sysrq-trigger
   echo p >/proc/sysrq-trigger
   echo m >/proc/sysrq-trigger

With the patch, the output flushes to the console immediately.
