From 55e50ace1ef4f358ba964737c3849a5a4a611eae Mon Sep 17 00:00:00 2001 From: David Greenman Date: Tue, 3 Sep 1996 07:13:56 +0000 Subject: [PATCH] Implemented user side of "noatime" mount option. This option disables the file access time update on reads and can be useful in reducing filesystem overhead in cases where the access time is not important (like Usenet news spools). --- sbin/mount/mntopts.h | 4 +++- sbin/mount/mount.c | 1 + sbin/mount_ifs/mntopts.h | 4 +++- sbin/mount_ifs/mount.c | 1 + 4 files changed, 8 insertions(+), 2 deletions(-) diff --git a/sbin/mount/mntopts.h b/sbin/mount/mntopts.h index 710b557e61a3..032d70ed5316 100644 --- a/sbin/mount/mntopts.h +++ b/sbin/mount/mntopts.h @@ -42,7 +42,8 @@ struct mntopt { /* User-visible MNT_ flags. */ #define MOPT_ASYNC { "async", 0, MNT_ASYNC, 0 } -#define MOPT_NOAUTO { "auto", 1, 0, 0 } +#define MOPT_NOATIME { "atime", 1, MNT_NOATIME, 0 } +#define MOPT_NOAUTO { "auto", 1, 0, 0 } #define MOPT_NODEV { "dev", 1, MNT_NODEV, 0 } #define MOPT_NOEXEC { "exec", 1, MNT_NOEXEC, 0 } #define MOPT_NOSUID { "suid", 1, MNT_NOSUID, 0 } @@ -69,6 +70,7 @@ struct mntopt { /* Standard options which all mounts can understand. */ #define MOPT_STDOPTS \ MOPT_FSTAB_COMPAT, \ + MOPT_NOATIME, \ MOPT_NOAUTO, \ MOPT_NODEV, \ MOPT_NOEXEC, \ diff --git a/sbin/mount/mount.c b/sbin/mount/mount.c index 286c2a0918c0..5592a632ce42 100644 --- a/sbin/mount/mount.c +++ b/sbin/mount/mount.c @@ -88,6 +88,7 @@ static struct opt { { MNT_ASYNC, "asynchronous" }, { MNT_EXPORTED, "NFS exported" }, { MNT_LOCAL, "local" }, + { MNT_NOATIME, "noatime" }, { MNT_NODEV, "nodev" }, { MNT_NOEXEC, "noexec" }, { MNT_NOSUID, "nosuid" }, diff --git a/sbin/mount_ifs/mntopts.h b/sbin/mount_ifs/mntopts.h index 710b557e61a3..032d70ed5316 100644 --- a/sbin/mount_ifs/mntopts.h +++ b/sbin/mount_ifs/mntopts.h @@ -42,7 +42,8 @@ struct mntopt { /* User-visible MNT_ flags. */ #define MOPT_ASYNC { "async", 0, MNT_ASYNC, 0 } -#define MOPT_NOAUTO { "auto", 1, 0, 0 } +#define MOPT_NOATIME { "atime", 1, MNT_NOATIME, 0 } +#define MOPT_NOAUTO { "auto", 1, 0, 0 } #define MOPT_NODEV { "dev", 1, MNT_NODEV, 0 } #define MOPT_NOEXEC { "exec", 1, MNT_NOEXEC, 0 } #define MOPT_NOSUID { "suid", 1, MNT_NOSUID, 0 } @@ -69,6 +70,7 @@ struct mntopt { /* Standard options which all mounts can understand. */ #define MOPT_STDOPTS \ MOPT_FSTAB_COMPAT, \ + MOPT_NOATIME, \ MOPT_NOAUTO, \ MOPT_NODEV, \ MOPT_NOEXEC, \ diff --git a/sbin/mount_ifs/mount.c b/sbin/mount_ifs/mount.c index 286c2a0918c0..5592a632ce42 100644 --- a/sbin/mount_ifs/mount.c +++ b/sbin/mount_ifs/mount.c @@ -88,6 +88,7 @@ static struct opt { { MNT_ASYNC, "asynchronous" }, { MNT_EXPORTED, "NFS exported" }, { MNT_LOCAL, "local" }, + { MNT_NOATIME, "noatime" }, { MNT_NODEV, "nodev" }, { MNT_NOEXEC, "noexec" }, { MNT_NOSUID, "nosuid" },
