New version of the qcow2 cache patches:
v2:
- Don't do pointer arithmetic on void *
- Rename table_addr() to qcow2_cache_get_table_addr()
- Add qcow2_cache_get_table_idx()
- Cast cache size to size_t to prevent overflows
- Make qcow2_cache_put() a void function
- Don't store the cluster size in the cache, get it from the BDS instead
v1: https://lists.nongnu.org/archive/html/qemu-devel/2015-04/msg04355.html
Regards,
Berto

qcow2: use an LRU algorithm to replace entries from the L2 cache
qcow2: remove qcow2_cache_find_entry_to_replace()
qcow2: use a hash to look for entries in the L2 cache
qcow2: make qcow2_cache_put() a void function
qcow2: style fixes in qcow2-cache.c
