Subject: [PATCH] block/gluster: correctly set max_pdiscard which is int64_t
|
|
|
|
Previously, max_pdiscard would be zero in the following assertion:
|
|
qemu-system-x86_64: ../block/io.c:3166: bdrv_co_pdiscard: Assertion
|
|
`max_pdiscard >= bs->bl.request_alignment' failed.
|
|
|
|
Fixes: 0c8022876f ("block: use int64_t instead of int in driver discard handlers")
