From ec3df9e65a3a2e1005cd4d50d06a8819fd3ab5f6 Mon Sep 17 00:00:00 2001 From: Anoop C S Date: Tue, 19 Jan 2016 14:35:18 +0530 Subject: libgfapi: Add new api for supporting mandatory-locks The current API for byte-range locks [glfs_posix_lock()] doesn't allow applications to specify whether it is advisory or mandatory type locks. This particular change is to introduce an extended byte-range lock API with an additional argument for including the byte-range lock mode to be one among advisory(default) or mandatory. Patch also includes a gfapi test case which make use of this new api to acquire mandatory locks.
