[Qemu-devel] [PATCH v2 0/7] qcow2 L2/refcount cache improvements

[Alberto Garcia <berto@igalia.com>]

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
