Subject: [PATCH] kexec: followup to STATUS patch v3 already in staging
Date: Wed, 18 Jan 2017 15:47:26 -0600	[thread overview]
Message-ID: <1484776048-8995-1-git-send-email-eric.devolder@oracle.com> (raw)

This contains the two corrections pointed out by Jan Beulich
for the kexec STATUS call just introduced.

Note: In kexec_status(), the use of test_bit() can also return
EPERM, so the return value from test_bit() must be checked to
ensure that kexec_status() always returns 0, 1 or -1, per the
public header description.

Note: My handling of the test_bit() scenario is to explicitly
check for return value of 1, so any value other than 1 causes
kexec_status to return 0.
