Hi all,
I have created a real-time partition as follows.
root@node2:~# mkfs.xfs -f -r rtdev=/dev/sda3 /dev/sda4
meta-data=/dev/sda4 isize=256 agcount=4, agsize=56122440 blks
= sectsz=512 attr=2, projid32bit=0
data = bsize=4096 blocks=224489757, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal log bsize=4096 blocks=109614, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =/dev/sda3 extsz=4096 blocks=14865657,
rtextents=14865657
I wonder how to use its real-time feature. And I should call some interfaces
supported by XFS in the user/kernel-space, right?

Thanks
