Subject: signal.h: use an explicit cast to silent compiler warnings
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=141ae8478e2c45ce1ac9b480a979d7fa0f7fbc72;p=linux-kernel-docs%2Flinux-2.4.36.git

signal.h: use an explicit cast to silent compiler warnings

This patches include/linux/signal.h
There is an implicit cast from an integer to an
unsigned long (sigset_t) which causes compilers to generate warnings.
Different compilers could possibly produce different code.
This change has been tested over several years of use and is stable.
