0029 test set name: block06
0030
0031 Test 1: Get task 0 to get buffer 0 from the pool then release it twice.
0032
0033 Test 2: Get task 0 to get buffers 0 -> 4 from the pool hold them. Then get
0034 task 1 and task 2 to get them with blocking. The 2 tasks tests the
0035 priority blocking on the buffer.
0036
0037 Test 3: Read a block from disk into the buffer, modify the block and release
0038 it modified. Use a block great then 4 because 0 -> 4 are in the cache.
0039
0040 Test 4: Read every buffer in the pool and hold. Then get task 1 to ask for
0041 another buffer that is being accessed. It will block waiting for it to
0042 appear.
0043
0044 Test 5: Read every buffer in the pool and hold. Then get task 1 to ask for a
0045 new buffer. It will block waiting for one to appear.
0046
0047 Test 6: Get 5 buffers, release modify 4 then sync the last.
0048
0049 Test 7: Get 5 buffers, release modify them all then sync the device.
0050
0051 Test 8: Get 5 buffers, release modify the last 2 then the reset from 0.
