From cda9dd4207aeb29d0aa2298085cc2d1ebcb87e04 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Tue, 14 Jun 2016 12:24:50 -0500 Subject: gfs2: Large-filesystem fix for 32-bit systems Commit ff34245d switched from iget5_locked to iget_locked among other things, but iget_locked doesn't work for filesystems larger than 2^32 blocks on 32-bit systems. Switch back to iget5_locked. Filesystems larger than 2^32 blocks are unrealistic to work well on 32-bit systems, so this is mostly a code cleanliness fix.
