[PATCH] D95490: Support: Extract fs::resize_file_before_mapping_readwrite from FileOutputBuffer

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

If I understand correctly, uploading a new patch triggered new build and test results, and now the reported size is 4096:

So I think everything is working, it's just that mapping the file region on Windows seems to have a side effect of rounding the file size up to a multiple of the page size. So, the solution might be to change 123 to 4096 and hope for the best.

Code looks good to me, though.
