From 4c63c2454eff996c5e27991221106eb511f7db38 Mon Sep 17 00:00:00 2001 From: Luke Dashjr Date: Thu, 29 Oct 2015 08:22:21 +0000 Subject: btrfs: bugfix: handle FS_IOC32_{GETFLAGS,SETFLAGS,GETVERSION} in btrfs_ioctl 32-bit ioctl uses these rather than the regular FS_IOC_* versions. They can be handled in btrfs using the same code. Without this, 32-bit {ch,ls}attr fail.
