[PVFS-users] IS_DEADDIR and pvfs_revalidate_inode

[Rob Ross]

Christoph,

That condition can occur when a directory is deleted but files in the 
directory are still open.

We were also seeing this happen in cases that we didn't expect, thus the 
error message.

What type of access patterns are causing this for you?

Thanks,

Rob
