Our qapi conventions document that '.' should only be used in
the prefix of downstream names. BlkdebugEvent was a lone
exception to this. Changing this is not backwards compatible
to the 'blockdev-add' QMP command; however, that command is
not yet fully stable. It can also be argued that the testsuite
is the biggest user of blkdebug, and that any other user can
be taught to deal with the change by paying attention to
introspection results.
Done with:
$ for str in \
l1_grow.{alloc,write,activate}_table \
l2_alloc.{cow_read,write} \
refblock_alloc.{hookup,write,write_blocks,write_table,switch_table} \
pwritev_rmw.{head,after_head,tail,after_tail}; do
str1=$(echo "$str" | sed 's/\./\\./')
str2=$(echo "$str" | sed 's/\./_/')
git grep -l "$str1" | xargs -r sed -i "s/$str1/$str2/g"
done
followed by a manual touchup to test 77 to keep the test working.
