* MFC r307755: swapoff: Remove only late devices with -aL.jilles2016-11-191-1/+7
| | | | | | | | | | | | | | | Currently, '/etc/rc.d/swaplate stop' removes all swap devices. This can be very slow and may not even be possible if there is a lot of swap space in use. However, removing swap devices is only needed for late swap devices that may depend on daemons that subsequent shutdown steps stop. Normal swap devices such as hard disk partitions will remain available throughout the shutdown process and need not be removed. In swapoff, interpret -aL to remove late swap devices only, and use this in etc/rc.d/swaplate. The meaning of -aL in swapon remains unchanged (add all swap devices, both normal and late). PR: 187081

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | device names "md" or "md[0-9]*" and a "file" option are specified in /etc/fstab like this: md none swap sw,file=/swap.bin 0 0 - Add GBDE/GELI encrypted swap space specification support, which rc.d/encswap supported. The /etc/fstab lines are like the following: /dev/ada1p1.bde none swap sw 0 0 /dev/ada1p2.eli none swap sw 0 0 .eli devices accepts aalgo, ealgo, keylen, and sectorsize as options. swapctl(8) can understand an encrypted device in the command line like this: # swapctl -a /dev/ada2p1.bde - "-L" flag is added to support "late" option to defer swapon until rc.d/mountlate runs. - rc.d script change: rc.d/encswap -> removed rc.d/addswap -> just display a warning message if $swapfile is defined rc.d/swap1 -> renamed to rc.d/swap rc.d/swaplate -> newly added to support "late" option These changes alleviate a race condition between device creation/removal and swapon/swapoff.
