Subject: [PATCH] fs, proc: Add start_data, end_data, start_brk members to /proc/$pid/stat v2
Date: Mon, 5 Dec 2011 22:20:11 +0400 [thread overview]
Message-ID: <20111205182010.GV14515@moon> (raw)
It helps to dump and restore this mm_struct members.
v2:
- Kees and Alexey pointed out that "1" hack is unnecessary,
so make it to have plain (mm && permitted) ? mm->member : 0
form.
