Subject: sched: add macros to define bitops for task atomic flags
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4fce5e64991fc0a02e47e525ce72f33def17b7ef;p=pandora-kernel.git

sched: add macros to define bitops for task atomic flags

commit e0e5070b20e01f0321f97db4e4e174f3f6b49e50 upstream.

This will simplify code when we add new flags.

v3:
- Kees pointed out that no_new_privs should never be cleared, so we
shouldn't define task_clear_no_new_privs(). we define 3 macros instead
of a single one.

v2:
- updated scripts/tags.sh, suggested by Peter
