[Qemu-devel] [PATCH v3 0/3] Fix overflow bug in qcow2 discard |

v3: don't filter mapping info from qemu-img map output, otherwise
it don't show what I try to check [sorry for extra noise in list]
v2: [mostly by Eric's review]
01: new
02: point to bug introducing commit in cover letter [Eric]
[but I failed to compile it, to check]
drop s/INT_MAX/BDRV_REQUEST_MAX_BYTES/ chunk
03: - improve wording
- cheating with preallocation=metadata and discards
to make test quick and not eating disk space
- use new trace-point
- move it to be 250 iotest
- filter out extra qemu-img info output
Vladimir Sementsov-Ogievskiy (3):
block/qcow2-refcount: add trace-point to qcow2_process_discards
block/io: bdrv_pdiscard: support int64_t bytes parameter
iotests: test big qcow2 shrink
