* sysdeps/unix/sysv/linux/ia64/bits/shm.h (shmatt_t): New type.cvs/fedora-glibc-20051119T1959
(struct shmid_ds): Use it for shm_nattch field. 2005-11-18 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/futimesat.c (futimesat): If FILE is NULL, set access and modification times of the file referenced by FD. * sysdeps/generic/futimesat.c (futimesat): Don't return EINVAL if FILE is NULL. Don't check FD if FILE is absolute path. 2005-11-19 Ulrich Drepper <drepper@redhat.com> * nscd/nscd_gethst_r.c (nscd_gethst_r): Avoid unnecesary read call if there are no aliases. * sysdeps/unix/sysv/linux/Makefile (CFLAGS-connections.c, CFLAGS-pwdcache.c, CFLAGS-grpcache.c, CFLAGS-hstcache.c, CFLAGS-aicache.c, CFLAGS-initgrcache.c): Add -DHAVE_SENDFILE. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_SENDFILE): Define. * nscd/pwdcache.c [HAVE_SENDFILE]: Include <sys/sendfile.h> and <kernel-features.h>. [HAVE_SENDFILE] (cache_addpw): Use sendfile to transmit positive result. * nscd/grpcache.c: Likewise. * nscd/hstcache.c: Likewise. * nscd/aicache.c: Likewise. * nscd/initgrcache.c: Likewise. * nscd/connectionc.c: Likewise.
