#     Pull btrfs reverts from David Sterba:
#      "Due to a recent report [1] we need to revert the radix tree to xarray
#       conversion patches.
#     
#       There's a problem with sleeping under spinlock, when xa_insert could
#       allocate memory under pressure. We use GFP_NOFS so this is a real
#       problem that we unfortunately did not discover during review.
#     
#       I'm sorry to do such change at rc6 time but the revert is IMO the
#       safer option, there are patches to use mutex instead of the spin locks
#       but that would need more testing. The revert branch has been tested on
#       a few setups, all seem ok.
#     
#       The conversion to xarray will be revisited in the future"
