Re: [PATCH] target/file: don't zero iter before iov_iter_bvec

Pavel,
iov_iter_bvec() initialises iterators well, no need to pre-zero it beforehand as done in fd_execute_rw_aio(). Compilers can't optimise it out and generate extra code for that (confirmed with assembly).
Applied to 5.12/scsi-staging, thanks! -- Martin K. Petersen Oracle Linux Engineering
