    Btrfs: check if we can nocow if we don't have data space · 7ee9e440

    We always just try and reserve data space when we write, but if we are out of
    space but have prealloc'ed extents we should still successfully write.  This
    patch will try and see if we can write to prealloc'ed space and if we can go
    ahead and allow the write to continue.  With this patch we now pass xfstests
    generic/274.  Thanks,
