[PATCH nbdkit] log: Decode the extent type in output.
by Richard W.M. Jones
Instead of printing something like ‘type=0’ or ‘type=3’, this changes
the output to show the hole and zero flags separately. For example:
$ ./nbdkit -U - --filter=log sh - logfile=/dev/stdout \
--run 'qemu-img map $nbd' <<'EOF'
case "$1" in
get_size) echo 1M ;;
pread) dd if=/dev/zero count=$3 iflag=count_bytes ;;
can_extents) exit 0 ;;
extents)
echo "0 32K zero"
echo "32K 32K hole,zero"
echo "64K 983040 "
;;
*) exit 2 ;;
esac
EOF
[...]

[PATCH nbdkit] error: Fix all error-*-file parameters.
by Richard W.M. Jones
These didn't work because of copy and paste errors in
commit 086a1ceaeb8da4c67787c31580548f7a607b7a7c
and commit f649b53c037681e897471aa438758a07f067d624.
