pwrite(). Bug Fixed: LaunchPad: #764395 / MySQL bug #60788 (A. Kopytov)
- The maximum value for
innodb_use_purge_threadshas been corrected to32(maximum number of parallel threads in a parallelized operation). The innodb_purge_thread patch accepted a value up to 64 for theinnodb_use_purge_threadvariable, leading to an assertion failure for greater than the actual maximum. Bug Fixed: #755017 (L. Biveinis)
