The patch titled signals: use HAVE_SET_RESTORE_SIGMASK has been added to the -mm tree. Its filename is signals-use-have_set_restore_sigmask.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find out what to do about this The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: signals: use HAVE_SET_RESTORE_SIGMASK From: Roland McGrath <roland@xxxxxxxxxx> Change all the #ifdef TIF_RESTORE_SIGMASK conditionals in non-arch code to #ifdef HAVE_SET_RESTORE_SIGMASK. If arch code defines it first, the generic set_restore_sigmask() using TIF_RESTORE_SIGMASK is not defined.
