Subject: [PATCH 1/2] coredump: binfmt_elf_fdpic: don't use sub-thread's ->mm
Date: Wed, 16 Jul 2008 17:53:58 +0400 [thread overview]
Message-ID: <20080716135358.GA1216@tv-sign.ru> (raw)
Change binfmt_elf_fdpic.c:fill_prstatus() to use current->mm instead of p->mm.
They are equal, but with the next patch p->mm == NULL.
