nilfs_cleanerd not started for mount with relative pathname

[dexen deVries <dexen.devries@xxxxxxxxx>]

Hi,


when testing my other patches, the following came up:

with absolute pathname:
# mount /dev/sdb2 /mnt/x
# ps ax | grep [n]ilfs_cleanerd
30408 ?        Ss     0:00 /sbin/nilfs_cleanerd -n /dev/sdb2 /mnt/x


with relative mountpoint pathname:
# umount /mnt/x
# cd /mnt
# mount /dev/sdb2 x
# ps ax | grep [n]ilfs_cleanerd
((no such process))

with relative device pathname:
# umount /mnt/x
# cd /dev
# mount sdb2 /mnt/x
# ps ax | grep [n]ilfs_cleanerd
((no such process))

This is due to chdir(ROOTDIR) in daemonize(); currently daemonize is always 
called with nochdir == 0. Should I hardcode it to nochdir == 1 or canonicalize 
the `dev' and `dir' arguments with myrealpath()?
