Currently, the metadata cache size is only tunable on compile time
through macros. However, some users may want to use the minimal cache
size (for whatever reason) and others may want to increase the cache
size because they have enough memory and want to increase performance.
This series adds runtime options for setting the cache size in bytes
(which is an easily comprehensible unit) in various ways (by setting
each cache explicitly or the total size).
This series (patch 2) depends on Markus' series
"[PATCH v2 0/4] block: Use g_new() & friends more".
Max Reitz (4):
qcow2: Constant cache size in bytes
qcow2: Use g_try_new0() for cache array
qcow2: Add runtime options for cache sizes
iotests: Add test for qcow2's cache options
