Subject: [PATCH] sys_signal: initialize ->sa_mask
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c70d3d703ad94727dab2a3664aeee33d71e00715;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] sys_signal: initialize ->sa_mask

Pointed out by Linus Torvalds.

sys_signal() forgets to initialize ->sa_mask.

( I suspect arch/ia64/ia32/ia32_signal.c:sys32_signal()
  also needs this fix )
