Subject: usbatm_heavy_init: don't use CLONE_SIGHAND
X-Git-Tag: v2.6.22-rc1~209
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b8a124da9261873e3e3541898d5c46d273afee34;p=linux-2.6

usbatm_heavy_init: don't use CLONE_SIGHAND

usbatm_do_heavy_init() calls allow_signal() which plays with parent process's
->sighand.
