6 years agoFix problem with terminating on unaligned sizes

Fix problem with terminating on unaligned sizes

Three separate little issues:

- Don't round up the number of blocks needed. That means we end
  up with potential partial blocks, which we can never do IO to.

- Fix an axmap bug where we only check against the specific bit
  in the mask, but we really want to check for "this bit or any
  higher bit". This makes axmap_next_free() behave more like it
  should, instead of failing way too often.

- For the almost-full case, we can return a next available bit
  that is just outside the allowed range. Punt to first-free for
  that case.

Taking a look to the debugging output shows that on write action the

be written. However, for open and close we have a different fileno value
for each file. Taking a look into the source code of read_iolog2()
reveals why: In case of actions 'open' or 'close', 'fileno' is looked up
through 'get_fileno(td, fname)', but for 'write', 'read' and the other 4
argument actions 'fileno' is not looked up. When I add a 'fileno =
get_fileno(td, fname);' at the end of the '(r == 4)' branch, I/Os are
replayed to the designated files.
