* readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
* automount: implement expire
* automount: implement expire:
- set superblock timeout AUTOFS_DEV_IOCTL_TIMEOUT_CMD
- periodically run AUTOFS_DEV_IOCTL_EXPIRE_CMD
- every timeout/4 (original autofs logic)
- blocking, needs a thread
- run until -EAGAIN
- receive expire packet on pipe if kernel tells the timeout is over
- call umount
- answer expire packet on pipe with AUTOFS_DEV_IOCTL_{READY,FAIL}_CMD
- AUTOFS_DEV_IOCTL_EXPIRE_CMD returns
* services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)
