Jan Lindström 752ba087c8 MDEV-5746: Slow file extend when innodb_use_fallocate=1 and SSD 
file storage.

Analysis: posix_fallocate was called using 0 as offset and len as
desired size. This is not optimal for SSDs.

Fix: Call posix_fallocate with correct offset i.e. current file size
and extend the file from there len bytes.

CMakeLists.txt MDEV-5247: DB locked up at btr0cur.c line 568. There is inconsistent and non logical usage of have_LRU_mutex and incorrect value on ha_innodb.cc when buf_LRU_free_block is called. Additionally, for future long semaphore wait cases added a new configuration variable innodb_use_stacktrace. If this variable is true a signal handler for SIGUSR2 is installed when InnoDB server starts and when a long semaphore wait is detected at sync/sync0array.c we send SIGUSR2 signal to waiting thread and thread that has acuired RW-latch. For both threads a full stacktrace is produced as well as its is possible. 2013-11-14 12:57:28 +02:00
