Hi Eric, Today's linux-next merge of the userns tree got a conflict in include/linux/fs.h between commit 89e9b9e07a39 ("writeback: add {CONFIG|BDI_CAP|FS}_CGROUP_WRITEBACK") from the block tree and commit 1b852bceb0d1 ("mnt: Refactor the logic for mounting sysfs and proc in a user namespace") from the userns tree. I fixed it up (see below) and can carry the fix as necessary (no action is required). -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx diff --cc include/linux/fs.h index fe0dcaa3a789,571aab91bfc0..000000000000 --- a/include/linux/fs.h +++ b/include/linux/fs.h @@@ -1913,7 -1897,7 +1913,8 @@@ struct file_system_type #define FS_HAS_SUBTYPE 4 #define FS_USERNS_MOUNT 8 /* Can be mounted by userns root */ #define FS_USERNS_DEV_MOUNT 16 /* A userns mount does not imply MNT_NODEV */ - #define FS_CGROUP_WRITEBACK 32 /* Supports cgroup-aware writeback */ + #define FS_USERNS_VISIBLE 32 /* FS must already be visible */ ++#define FS_CGROUP_WRITEBACK 64 /* Supports cgroup-aware writeback */ #define FS_RENAME_DOES_D_MOVE 32768 /* FS will handle d_move() during rename() internally. */ struct dentry *(*mount) (struct file_system_type *, int, const char *, void *);
