Hi,

I've got an embedded system running a modified 2.6.27 (yes, we're trying to upgrade) and we're running into a scenario where something is happening that causes accesses to *all* XFS filesystems to hang or be delayed for some time.

I know it may be a bit of a stretch since the kernel is old, but I was wondering if you might have any suggestions as to what I might look at as far as locks/algorithms within XFS that would affect all filesystems.

In case it matters, the hardware is fairly beefy-- 32 threads of Sandy Bridge CPU, 64GB RAM, SAS drives, etc.

Chris
