I built this for RHELAS4U2 x86_64 with the 2.6.9-22.ELsmp kernel.

I did enable the xfs_direct_io_locking.patch (see inside 
kernel-module-xfs.spec for details).

However, I run into issues with xfs_freeze as it often locks up when I 
try to freeze a file system where there is I/O activity. Sometimes it 
happen on the first xfs_freeze invocation to freeze the file system, 
other times I have to unfreeze and then it happens on the second time I 
freeze. xfs_freeze never returns when this happens.

Looks like xfs_io get stuck --see partial output from `ps auxf`:

strace -ff -o freeze.txt xfs_freeze -f /mnt/xfs
  \_ /bin/sh -f /usr/sbin/xfs_freeze -f /mnt/xfs
      \_ /usr/sbin/xfs_io -r -p xfs_freeze -x -c freeze /mnt/xfs

Anyone else encountering this issue?
