Subject: [PATCH] Linux 3.13 compat: Remove unused flags variable from
|
||
__cv_init()
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8

|
||
|
||
GCC 4.8.1 complained about an unused flags variable when building
|
||
against Linux 2.6.26.8:
|
||
|
||
/var/tmp/portage/sys-kernel/spl-9999/work/spl-9999/module/spl/../../module/spl/spl-condvar.c:
|
||
In function ‘__cv_init’:
|
||
/var/tmp/portage/sys-kernel/spl-9999/work/spl-9999/module/spl/../../module/spl/spl-condvar.c:39:6:
|
||
error: variable ‘flags’ set but not used
|
||
[-Werror=unused-but-set-variable]
|
||
int flags = KM_SLEEP;
|
||
^
|
||
cc1: all warnings being treated as errors
|
||
|
||
Additionally, the superfluous code uses a preempt_count variable that is
|
||
no longer available on Linux 3.13. Deleting the unnecessary code fixes a
|
||
Linux 3.13 compatibility issue.
