Subject: Orangefs: don't propogate whacky error codes
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=cf546ab6b189ab8b3acb26bbc2f0af4df21f16c7;p=openwrt%2Fstaging%2Fblogic.git

Orangefs: don't propogate whacky error codes

When we get an error return code from userspace (the client-core)
we check to make sure it is a valid code.

This patch maps the whacky return code to -EINVAL instead of
propagating garbage back up the call chain potentially resulting
in a hard-to-find train-wreck.

The client-core doesn't have any business returning whacky return
codes, but if it does, we don't want the kernel to crash as a result.
