The comment is incorrect: the function doesn't check if buf's memblock
is large enough to hold 'size' bytes. What it does is to check if buf's
memblock is large enough to hold 'buf->length' bytes, and the caller is
expected to tell the current memblock size with the 'size' variable.
(Perhaps "current_block_size" would be a more informative variable
name?)
I wonder if it would be possible to change the code match the comment
instead of changing the comment to match the code, since the comment
that you wrote describes a much saner system...

CC pulsecore/libpulsecore_4.0_la-resampler.lo
pulsecore/resampler.c: In function 'fit_buf':
pulsecore/resampler.c:1149:9: warning: ISO C90 forbids mixed declarations and
code [-Wdeclaration-after-statement]
pa_memblock *new_block = pa_memblock_new(r->mempool, size);
^
Please put variable declarations to the beginning of a code block.
There was also a fit_buf() call in convert_to_work_format() that was
updated only in a later patch, so this patch didn't compile.
