From 86066914edff2316cbed63aac8a87d5001441a16 Mon Sep 17 00:00:00 2001 From: Abhi Das Date: Tue, 9 Jun 2015 09:16:46 -0500 Subject: [PATCH] gfs2: Don't support fallocate on jdata files We cannot provide an efficient implementation due to the headers on the data blocks, so there doesn't seem much point in having it.
