Subject: [PATCH 1/2] compat ABI: use non-compat openat and open_by_handle_at variants
Date: Tue, 8 Nov 2016 16:02:59 +0530 [thread overview]
Message-ID: <1478601180-20932-2-git-send-email-ynorov@caviumnetworks.com> (raw)
In-Reply-To: <1478601180-20932-1-git-send-email-ynorov@caviumnetworks.com>
The only difference is that non-compat version forces O_LARGEFILE,
and it should be the default behaviour for all architectures, as
we don't support 32-bit off_t. The only exception is tile32, that
continues with compat version of syscalls.
