Thanks David. The patch is applied in cvs trunk now, with some minor
formatting updates.

We ran into a scenario where some signal interrupts were being caught in
the middle of PVFS2 calls and then the pvfs2 client ended up in a bad
state where any accesses to a particular directory would always return
(Permission Denied). This was with the 2.6 base PVFS2 code on RHEL3
clients. The system interrupts seemed to cause various other issues on
RHEL4 and RHEL5 systems, but different than RHEL3.
Working through some test cases where we could reliably
reproduce this, we came up with this patch. It might not be the perfect
solution, but it seems to keep us out of that scenario.
This patch also has logging changes/updates that we used to
help track down the problem. Not sure what all would be useful, but the
main changes are in dcache.c and kernel.h.
Thanks,
