Subject: On using allocation in sysctl handler
Date: Sat, 27 Mar 2010 11:56:08 +0100 [thread overview]
Message-ID: <17cb70ee1003270356g7fba07b0xf558583484748dc3@mail.gmail.com> (raw)
Hi,
I added an allocation GFP_KERNEL inside a sysctl handler and got the error
BUG: sleeping function called from invalid context
in_atomic(): 1, irqs_disabled(): 0, pid: 723, name: sysctl
Is it obvious error and I should use GFP_ATOMIC?
I guess yes, but it just happens since I switched to a 2.6.30 on ppc, and it did
not happen on 2.6.30 x86.
So I'm not sure if something is wrong on ppc, of if something changed
recently in sysctl,
or simply my code was wrong and the check has improved in memory system.
Thanks,
Auguste.
