Hi,

I seem hitting a regression of NFS client on the today's Linus git
tree.  The symptom is that the file read over NFS returns occasionally
-EACCESS at the first read.  When I try to read the same file again
(or do some other thing), I can read it successfully.

The git bisection leaded to the commit
bd8b2441742b49c76bec707757bd9c028ea9838e
    NFS: Store the raw NFS access mask in the inode's access cache


Any further hint for debugging?


thanks,

Takashi
