This is just a couple of additional functions for xfs_io I have had
sitting around for a while. The first is an interface to
sync_file_range() for better control of file writeback. The second
and third introduce vectored pread/pwrite so that I could simulate
the same style of vectored IO that KVM does via direct IO (hint -
tracing indicated that the generic direct IO code doesn't handle
this particularly efficiently).

Looks like this might need some config-fu:
pread.o: In function `do_pread':
/src/git/xfsprogs/io/pread.c:198: undefined reference to `preadv'
/src/git/xfsprogs/io/pread.c:198: undefined reference to `preadv'
pwrite.o: In function `do_pwrite':
/src/git/xfsprogs/io/pwrite.c:85: undefined reference to `pwritev'
/src/git/xfsprogs/io/pwrite.c:85: undefined reference to `pwritev'
sync_file_range.o: In function `sync_range_f':
/src/git/xfsprogs/io/sync_file_range.c:87: undefined reference to `sync_file_range'
(on a Centos5 box)
Thanks Eric, I will take a look at it.
