[bug] sleeping function called from illegal context

[Alex]

I got the following error logged:
(Not sure if the two are connected in some way)
The problem seems to be somewhere in xfs.

Linux <snip> 2.5.46 #1 Wed Nov 6 02:10:38 EST 2002 i686 AMD Duron(TM)Processor AuthenticAMD GNU/Linux

The kernel is configured preemptible, with xfs builtin with no extra xfs
options.

Alex Khripin
