/proc/$PID/net currently allows the setting of file attributes,
in contrast to other /proc/$PID/ files and directories.
This would break the nolibc testsuite so the first patch in the series
removes the offending testcase.
The "fix" for nolibc-test is intentionally kept trivial as the series
will most likely go through the filesystem tree and if conflicts arise,
it is obvious on how to resolve them.
Technically this can lead to breakage of nolibc-test if an old
nolibc-test is used with a newer kernel containing the fix.
Note:
Except for /proc itself this is the only "struct inode_operations" in
fs/proc/ that is missing an implementation of setattr().
