Subject: [PATCH] xfsprogs: remove unreachable code in libxfs_inode_alloc
Date: Mon, 06 Apr 2015 12:28:14 -0500	[thread overview]
Message-ID: <5522C22E.4000107@redhat.com> (raw)

This code does:

        if (!ialloc_context && !ip)
                return;

        // if !ip here, ialloc_context must be true

        if (ialloc_context) {
                ...
                if (!ip)
                        error = ENOSPC;
                if (error)
                        return error;
                // if !ip in this block we've returned
        }

        // so (!ip) cannot be true here
        if (!ip)
                error = ENOSPC;

(cherry picked this one out of Coverity reports)
