log_write_up_to(): Replace if-else if-else with a switch block.
log_archive_do(): Remove an excess mutex_enter(). Replace if-else if-else
with a switch block. (This function is not included unless UNIV_LOG_ARCHIVE
is defined.)
buf_page_get_gen(): Cache the result of fil_space_get_zip_size().
trx_commit_off_kernel(): Eliminate the flag must_flush_log. Initialize lsn = 0
to signify must_flush_log == FALSE.
log_flush_margin(): Eliminate the flag do_flush. Initialize lsn = 0
to signify do_flush == FALSE.
buf_pool_t: Remove n_frames, max_size, and blocks_of_frames.
The current buffer pool size is in curr_size.
buf_pool_init(): Remove parameter max_size.
buf_pool_get_max_size(), buf_pool_is_block(): Remove.
buf_block_align(): Do not assume that the buffer pool is allocated
in one chunk. Replace dependency on buf_pool->blocks_of_frames
with a call to buf_page_hash_get().
fil_read(), fil_write(): Make these inlined functions in fil0fil.c.
fil_write_lsn_and_arch_no_to_file(): Remove the parameter space_id and
