[PATCH] D115957: [Support] Revert posix_fallocate in resize_file

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Thanks! I'll wait few days and push.  If posix_fallocate is to be restored, I believe it should be passed explicitly as a flag, and there should be higher justification for lld/ELF. 
I've noted this thing in https://maskray.me/blog/2021-12-19-why-isnt-ld.lld-faster#open-output-file
