Patch series "ocfs2: fix nfsd over ocfs2 issues", v2. This is a series of patches to fix issues on nfsd over ocfs2. patch 1 is to avoid inode removed while nfsd access it patch 2 & 3 is to fix a panic issue. This patch (of 4): When nfsd is getting file dentry using handle or parent dentry of some dentry, one cluster lock is used to avoid inode removed from other node, but it still could be removed from local node, so use a rw lock to avoid this.

IDE warm-plug HOWTO
===================
To warm-plug devices on a port 'idex'::
# echo -n "1" > /sys/class/ide_port/idex/delete_devices
unplug old device(s) and plug new device(s)::
# echo -n "1" > /sys/class/ide_port/idex/scan
done
NOTE: please make sure that partitions are unmounted and that there are
no other active references to devices before doing "delete_devices" step,
also do not attempt "scan" step on devices currently in use -- otherwise
results may be unpredictable and lead to data loss if you're unlucky
