[Bug nptl/11799] New: si_code is not SI_USER on raise()

[jan dot kratochvil at redhat dot com]

si_code is SI_TKILL in such case but:
./sysdeps/unix/sysv/linux/bits/siginfo.h:
  SI_USER,			/* Sent by kill, sigsend, raise.  */

kernel-2.6.33.5-124.fc13.x86_64
glibc-2.12-2.x86_64 and HEAD (5be9d05d3136460cf6cedd3823fd236aeebe83ef)

Just noticed, unaware of any problem due to it.

--- Comment #3 from Michael Kerrisk <mtk.manpages at gmail dot com> 2012-04-20 01:18:23 UTC ---
Around glibc 2.3.2/2.3.3, the implementation of raise() changed, resulting in a
silent ABI change to the si_code behavior. Once upon a time, the code comment
was true.

That is no problem except in the documentation.  No standard specifies anything
about the si_code used for raise.  I changed the documentation.
