Subject: [PATCH] fix up ext2_fs.h for userspace after reservations backport

From: Tobias Poschwatta <tp@...z.de>

In commit a686cd898bd999fd026a51e90fb0a3410d258ddb:

 "Val's cross-port of the ext3 reservations code into ext2."

include/linux/ext2_fs.h got a new function whose return value is only
defined if __KERNEL__ is defined. Putting #ifdef __KERNEL__ around the
function seems to help, patch below.

BR, Tobias
