Subject: sysctl extern cleanup: rtmutex
X-Git-Tag: v2.6.34-rc2~69
X-Git-Url: http://git.samba.org/?a=commitdiff_plain;h=4f0e056fdebc15d3f4724ebc7bbf323158add1d7;p=sfrench%2Fcifs-2.6.git

sysctl extern cleanup: rtmutex

Extern declarations in sysctl.c should be moved to their own header file,
and then include them in relavant .c files.

Move max_lock_depth extern declaration to linux/rtmutex.h
