From b8eca7ff8ca1cbc3e1d6bec2fed4213863fa441b Mon Sep 17 00:00:00 2001 From: Carlos O'Donell Date: Tue, 1 Dec 2009 10:45:41 -0500 Subject: [PATCH] Update constants and rearrange file. Update F_SETOWN_EX and F_GETOWN_EX. Rearrange the file to match other targets, reducing future diffs against other targets and making maintenance easier. --- ChangeLog.hppa | 7 ++ sysdeps/unix/sysv/linux/hppa/bits/fcntl.h | 119 +++++++++++++++++++----------- 2 files changed, 83 insertions(+), 43 deletions(-) diff --git a/ChangeLog.hppa b/ChangeLog.hppa index 24a152e..be0a71a 100644 --- a/ChangeLog.hppa +++ b/ChangeLog.hppa @@ -1,3 +1,10 @@ +2009-11-29 Carlos O'Donell + + * sysdeps/unix/sysv/linux/hppa/bits/fcntl.h: + Rearrange file to reduce future maintenance. + [__USE_GNU]: Update F_GETOWN_EX, and F_SETOWN_EX. + Define f_owner_ex an __pid_type. + 2009-11-25 Carlos O'Donell * sysdeps/unix/sysv/linux/hppa/nptl/bits/pthreadtypes.h: diff --git a/sysdeps/unix/sysv/linux/hppa/bits/fcntl.h b/sysdeps/unix/sysv/linux/hppa/bits/fcntl.h index a0b0e07..a2c6482 100644 --- a/sysdeps/unix/sysv/linux/hppa/bits/fcntl.h +++ b/sysdeps/unix/sysv/linux/hppa/bits/fcntl.h @@ -1,6 +1,6 @@ /* O_*, F_*, FD_* bit values for Linux/HPPA.
