*
- * 97-3-25 compiled 0-th version, not yet tested it
- * (it did not work, BTW) (later that day) HEY! it works!
- * (bit later) hmm, not that much... 2:00am next day:
- * yes, it works, but it gives something like 50kB/sec
- * 97-4-01 complete rewrite to make it possible for many requests at
- * once to be processed
- * 97-4-11 Making protocol independent of endianity etc.
- * 97-9-13 Cosmetic changes
- * 98-5-13 Attempt to make 64-bit-clean on 64-bit machines
- * 99-1-11 Attempt to make 64-bit-clean on 32-bit machines <ankry@mif.pg.gda.pl>
- * 01-2-27 Fix to store proper blockcount for kernel (calculated using
- * BLOCK_SIZE_BITS, not device blocksize) <aga@permonline.ru>
- * 01-3-11 Make nbd work with new Linux block layer code. It now supports
- * plugging like all the other block devices. Also added in MSG_MORE to
- * reduce number of partial TCP segments sent. <steve@chygwyn.com>
- * 01-12-6 Fix deadlock condition by making queue locks independent of
- * the transmit lock. <steve@chygwyn.com>
- * 02-10-11 Allow hung xmit to be aborted via SIGKILL & various fixes.
- * <Paul.Clements@SteelEye.com> <James.Bottomley@SteelEye.com>
- * 03-06-22 Make nbd work with new linux 2.5 block layer design. This fixes
- * memory corruption from module removal and possible memory corruption
- * from sending/receiving disk data. <ldl@aros.net>
- * 03-06-23 Cosmetic changes. <ldl@aros.net>
- * 03-06-23 Enhance diagnostics support. <ldl@aros.net>
- * 03-06-24 Remove unneeded blksize_bits field from nbd_device struct.
- * <ldl@aros.net>
- * 03-06-24 Cleanup PARANOIA usage & code. <ldl@aros.net>
- * 04-02-19 Remove PARANOIA, plus various cleanups (Paul Clements)
- * possible FIXME: make set_sock / set_blksize / set_size / do_it one syscall
- * why not: would need access_ok and friends, would share yet another
- * structure with userland
