That makes sense.  For 3.20, I added such information to the pages
where it is missing

gettimeofday(2)

[PATCH] Document signal-semantics changes of container-init


Hi Michael,

The kernel changes corresponding to his update were added to -mm
on 2009-02-19. Please review and let me know if other man pages
should be updated to document these semantics.

Subject: [PATCH] Document signal-semantics changes of container-init

Container-inits have some special signal semantics depending on
whether the signal was sent from the same container or a parent
container. These changes were implemented by the patchset:

Grr, failed to mention about SIGKILL/SIGSTOP from parent ns.
Here is an updated patch.

ptrace(PTRACE_SYSCALL) and data field

the ptrace(2) page doesnt say anything about the data field (ignored or 
otherwise).  it seems to be ignored, but i didnt trace the kernel 
exhaustively.  the examples found via google shows that it's ignored.  strace 
usage seems odd (it passes in an irrelevant pointer), which would indicate 
it's ignored as well ...

[Bug 12919] New: posix_fallocate: what if len == 0?

           Summary: posix_fallocate: what if len == 0?

Hi,

I noticed the following in the manpage for posix_fallocate.  It currently (in
man-pages 3.19) says under "Errors":

  EINVAL  offset or len was less than 0.

However, the Linux kernel also returns EINVAL if len is *equal* to 0.  (See
fallocate() in
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob_plain;f=fs/open.c;hb=HEAD).
 This follows IEEE Std 1003.1-2001, which says
(http://www.opengroup.org/onlinepubs/009695399/functions/posix_fallocate.html):

[EINVAL]
