Ok, commited these checkpatch fixes:

http://git.kernel.org/?p=linux/kernel/git/nab/lio-core-2.6.git;a=commitdiff;h=65808529e0ed76308842c87faccf4526fa8bb13d

Also, it looks like configfs_macros.h is triggering the same checkpatch
false-positive as target_core_configfs.c:

configfs_macros.h:138: ERROR: Macros with multiple statements should be enclosed in a do - while loop
configfs_macros.h:143: ERROR: Macros with multiple statements should be enclosed in a do - while loop

This is the case where macros with multiple statements exist containing
function defintions, which obviously cannot be included in a do {} while
loop.

Thanks Daniel,
