Previously, the atime-modifying vnops called ZFS_ACCESSTIME_STAMP() followed by zfs_inode_update() to update the atime. However, since atimes are cached in the znode for delayed writing, the zfs_inode_update() function would effectively ignore the cached atime by reading it from the SA. This commit moves the updating of the atime in the inode into zfs_tstamp_update_setup() which is called by the ZFS_ACCESSTIME_STAMP() macro and eliminates the call to zfs_inode_update() in the atime-modifying vnops. It's possible the same thing could have been done directly in zfs_inode_update() but I wasn't sure that it was safe in all cases where it is called. The effect is that atime handling is as if "strictatime" were selected; even if the filesystem is mounted with "relatime". Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #1949 |
