Fix gcc fortify source warnings
Resolve issues uncovered by -D_FORTIFY_SOURCE=2, the default redhat macro's file adds this option to the cflags. This causes warnings of the following type designed to keep the developer honest: warning: ignoring return value of 'foo', declared with attribute warn_unused_result The short term fix is to wrap these calls in VERIFY() to check the return code. The code was already assusing these would never fail. Signed-off-by: Brian Behlendorf <[email protected]>
