Revision bda8efec5c706a672e0714d341a342e811f0262a authored by Mikulas Patocka on 29 May 2011, 12:03:09 UTC, committed by Alasdair G Kergon on 29 May 2011, 12:03:09 UTC
Replace the arbitrary calculation of an initial io struct mempool size with a constant. The code calculated the number of reserved structures based on the request size and used a "magic" multiplication constant of 4. This patch changes it to reserve a fixed number - itself still chosen quite arbitrarily. Further testing might show if there is a better number to choose. Note that if there is no memory pressure, we can still allocate an arbitrary number of "struct io" structures. One structure is enough to process the whole request.
