Hello, this patch set fixes a problem introduced by commit 073931017b49 "posix_acl: Clear SGID bit when setting file permissions". The problem is that when new directory 'DIR1' is created in a directory 'DIR0' with SGID bit set, DIR1 is expected to have SGID bit set (and owning group equal to the owning group of 'DIR0'). However when 'DIR0' also has some default ACLs that 'DIR1' inherits, setting these ACLs will result in SGID bit on 'DIR1' to get cleared if user is not member of the owning group. The problem is fixed by moving posix_acl_update_mode() so that it does not get called when default ACLs are inherited. I have created new generic/441 test for this and verified that generic/314, generic/375, and generic/441 pass for ext2, ext4, btrfs, xfs, ocfs2, reiserfs. All patches in this series are completely independent so fs maintainers please pick them up as soon as they get reviewed. I'm leaving for three weeks of vacation at the end of the week so I won't be able to push this further for some time. Honza
