This is a theorical fix only and hasn't been tested on a file that actually runs this code path.

IIRC there is a memset() at the very beginning of btrfs_file_read() to set the whole dest memory to zero.

Right, sorry.

I'll drop this and send a new patch that removes the duplicate memset (at "The whole file is a hole" comment) instead as seeing multiple memsets is what made me think it'd be necessary without thinking; that can be done even if we rework the function a bit in later cleanups...
