From b00263d1cafdd667de56cde47f35d5ee8dd37e14 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Wed, 19 Mar 2014 09:10:21 -0400 Subject: [PATCH] GFS2: Increase the max number of ACLs This patch increases the maximum number of ACLs from 25 to 300 for a 4K block size. The value is adjusted accordingly if the block size is smaller. Note that this is an arbitrary limit with a performance tradeoff, and that the physical limit is slightly over 500.
