[Qemu-devel] [PATCH v4 00/17] block: local qiov helper

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

Hi all!

Here is a new simple helper for a very often patter
around qemu_iovec_init_external, when we need simple qiov with only
one iov, initialized from external buffer.

v4:
 01: tiny improvements by Eric
     + fix bug: s/niov/nalloc in assertion
     + rename s/qemu_iovec_get_buf/qemu_iovec_buf,
       to don't look like getter, which in turn should not return
       pointer to something internal to be freed separately.
     So, no r-b's in 01 
 07,10,16
    - rebase on new function name qemu_iovec_buf 
    - save r-b's by Eric and Stefan
 others unchanged, add r-b's by Eric and Stefan

v3:
  01-02: tiny improvements, described in patch-emails
  03-17: new patches

  Note: only hw/scsi/scsi-disk.c not updated, as it has too tricky
        logic around @iov fields of structures. So, it is simpler to
        keep it as is.

v2 was "[PATCH v2 0/2] block: local qiov helper: part I"
