Subject: sys_setpgid(): simplify pid/ns interaction
X-Git-Tag: v2.6.25-rc1~221
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4e021306cff4277764a42065214fc73f2d26be4b;p=pandora-kernel.git

sys_setpgid(): simplify pid/ns interaction

sys_setpgid() does unneeded conversions from pid_t to "struct pid" and vice
versa.  Use "struct pid" more consistently.  Saves one find_vpid() and
eliminates the explicit usage of ->nsproxy->pid_ns.  Imho, cleanups the
code.

Also use the same_thread_group() helper.
