+Subject: [PATCH] btrfs: provide fallback definitions for
+ BTRFS_IOC_QUOTA_RESCAN*
+
+<linux/btrfs.h> was introduced in linux v3.9-rc1 while some
+of btrfs ioctls were added later, e.g. BTRFS_IOC_QUOTA_RESCAN
+and BTRFS_IOC_QUOTA_RESCAN_STATUS in v3.10-rc2,
+or BTRFS_IOC_QUOTA_RESCAN_WAIT in v3.11-rc1.
+
+* btrfs.c [!BTRFS_IOC_QUOTA_RESCAN]
+(struct btrfs_ioctl_quota_rescan_args): New structure.
+(BTRFS_IOC_QUOTA_RESCAN, BTRFS_IOC_QUOTA_RESCAN_STATUS): New macros.
+[!BTRFS_IOC_QUOTA_RESCAN_WAIT] (BTRFS_IOC_QUOTA_RESCAN_WAIT): New macro.
+* tests/btrfs.c: Likewise.
