From 8c087b5183adab186a298f2d6ed39aefdcae413c Mon Sep 17 00:00:00 2001 From: Chris Ball Date: Wed, 4 Feb 2009 09:29:54 -0500 Subject: [PATCH] Btrfs: Handle SGID bit when creating inodes Before this patch, new files/dirs would ignore the SGID bit on their parent directory and always be owned by the creating user's uid/gid.
