I saw this pop up with some pynfs testing:
[ 123.609992] nfsd: non-standard errno: -7
...and -7 is -E2BIG. I think what happened is that XFS returned -E2BIG
due to some xattr operations with the ACL10 pynfs TEST (I guess it has
limited xattr size?).
Add a better mapping for that error since it's possible that we'll need
it. How about we convert it to NFSERR_FBIG? As Bruce points out, they
both have "BIG" in the name so it must be good.
Also, turn the printk in this function into a WARN() so that we can get
a bit more information about situations that don't have proper mappings.
