From 9bad96a8cc669a3b399b9d739b505fdc592acaa4 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Fri, 25 Jun 2021 16:23:14 +0200 Subject: export/fuse: Give SET_ATTR_SIZE its own branch In order to support changing other attributes than the file size in fuse_setattr(), we have to give each its own independent branch. This also applies to the only attribute we do support right now.
