Subject: [Drbd-dev] drbd sparse warnings
Date: Wed, 26 May 2010 19:04:03 -0700 [thread overview]
Message-ID: <20100526190403.fcf8d536.rdunlap@xenotime.net> (raw)
Hi,
When I build a Linux kernel with "make C=1" to invoke sparse,
I see 135 sparse warnings like (shorter list):
linux-2.6.34-git11/drivers/block/drbd/drbd_int.h:931:39: error: attribute 'require_context': unknown attribute

linux-2.6.34-git11/drivers/block/drbd/drbd_nl.c:701:77: error: attribute 'require_context': unknown attribute
What is the meaning and usage of require_context in drbd_int.h?
#ifdef __CHECKER__
# define __protected_by(x) __attribute__((require_context(x,1,999,"rdwr")))
# define __protected_read_by(x) __attribute__((require_context(x,1,999,"read")))
# define __protected_write_by(x) __attribute__((require_context(x,1,999,"write")))
# define __must_hold(x) __attribute__((context(x,1,1), require_context(x,1,999,"call")))
#else
# define __protected_by(x)
# define __protected_read_by(x)
# define __protected_write_by(x)
# define __must_hold(x)
#endif
thanks,
