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. Signed-off-by: Jeff Layton Signed-off-by: J.
