Btrfs: fix overlap of fs_info::flags values
Because the values of BTRFS_FS_EXCL_OP and BTRFS_FS_QUOTA_OVERRIDE overlap, we should change the value. First, BTRFS_FS_EXCL_OP was set to 14. commit171938e528
("btrfs: track exclusive filesystem operation in flags") Next, the value of BTRFS_FS_QUOTA_OVERRIDE was set to 14. commitf29efe2921
("btrfs: add quota override flag to enable quota override for CAP_SYS_RESOURCE") As a result, the value 14 overlapped, by accident. This problem is solved by defining the value of BTRFS_FS_EXCL_OP as 16, the flags are internal. Fixes:f29efe2921
