Author: Dodji Seketeli <dodji at redhat.com>
Date: Mon Oct 5 13:45:38 2009 +0200
Add a wrapper for inotify_init1 (vgbz #202315)
* coregrind/m_syswrap/priv_syswrap-linux.h: Declare the
sys_inotify_init1 wrapper.
* coregrind/m_syswrap/syswrap-linux.c: Add pre/post handlers for
the sys_inotify_init1 syscall.
* coregrind/m_syswrap/syswrap-amd64-linux.c: Insert the
sys_inotify_init1 wrapper in the wrappers table for the amd64 arch.
* coregrind/m_syswrap/syswrap-x86-linux.c: Likewise for the x86_32
arch.
