xfs support in redhat beta sever.

[Knut J Bjuland <knutjbj@xxxxxxxxx>]

xfs file system does not compile with kernel from redhat in severn.
Linux-2.4.20-xfs-ntpl .path does not apply cleanly since there has been
some change in xfs code in ac kernel. I'll try to update to cvs and
repatch it with linux-2.4.20-xfs-nptl.......


xfs_syncd.c: In function `syncd':
xfs_syncd.c:52: structure has no member named `sigmask_lock'
xfs_syncd.c:54: too many arguments to function `recalc_sigpending'
