Block patches for 5.2.0-rc1:
- Some nvme fixes (addressing problems spotted by Coverity) - Fix nfs compiling on mingw (and enable it in Cirrus) - Fix an error path in bdrv_co_invalidate_cache() (permission update was initiated, but not aborted) - Fix (on-error) roll back in bdrv_drop_intermediate(): Instead of inlining bdrv_replace_node() (wrongly), call that function - Fix for iotest 240 - Fix error handling in bdrv_getlength() - Be more explicit about how QCowL2Meta objects are handled - Cleanups -----BEGIN PGP SIGNATURE----- iQFGBAABCAAwFiEEkb62CjDbPohX0Rgp9AfbAGHVz0AFAl+pgCISHG1yZWl0ekBy ZWRoYXQuY29tAAoJEPQH2wBh1c9An3UIAJgnlgRopgBfaOxwp08fJxOzIllVsqIo QLrVxopFhufCL2mOUlP/UNAM/5Lwrti+vt6gWvAP0CqmIXyqnrQCCH1r2VxY5i+X qUDbj/3slscVCkGi24W9nfu6waV6dQLpXzKEvNjHaEhTp4H+Kje/TftczzVM7/mQ l8raTkzyxC27pHw0vLBCjOl1MoMqSYNxMpqHa+lCHqGIiBG+NthbnXFqdITmSspw 0vAP1rdmp5pGXThI4Lv7cBkVbjWZSTKi858JzGHR9Uv1PHaU/cVRmhhAyR3gB8VX 3QHOilEaH+maYwOuhISBRVit75j+lk4E4KZZXSupw+i9D4ttdSluz2o= =LV7z -----END PGP SIGNATURE----- Merge remote-tracking branch 'remotes/maxreitz/tags/pull-block-2020-11-09-v2' into staging Block patches for 5.2.0-rc1: - Some nvme fixes (addressing problems spotted by Coverity) - Fix nfs compiling on mingw (and enable it in Cirrus) - Fix an error path in bdrv_co_invalidate_cache() (permission update was initiated, but not aborted) - Fix (on-error) roll back in bdrv_drop_intermediate(): Instead of inlining bdrv_replace_node() (wrongly), call that function - Fix for iotest 240 - Fix error handling in bdrv_getlength() - Be more explicit about how QCowL2Meta objects are handled - Cleanups # gpg: Signature made Mon 09 Nov 2020 17:45:06 GMT # gpg: using RSA key 91BEB60A30DB3E8857D11829F407DB0061D5CF40 # gpg: issuer "mreitz@redhat.com" # gpg: Good signature from "Max Reitz <mreitz@redhat.com>" [full] # Primary key fingerprint: 91BE B60A 30DB 3E88 57D1 1829 F407 DB00 61D5 CF40 * remotes/maxreitz/tags/pull-block-2020-11-09-v2: block: make bdrv_drop_intermediate() less wrong block: add bdrv_replace_node_common() block: add forgotten bdrv_abort_perm_update() to bdrv_co_invalidate_cache() block: Fix some code style problems, "foo* bar" should be "foo *bar" block: Fix integer promotion error in bdrv_getlength() block: enable libnfs on msys2/mingw in cirrus.yml block: Fixes nfs compiling error on msys2/mingw iotests: rewrite iotest 240 in python iotests: add filter_qmp_virtio_scsi function hw/block/nvme: fix free of array-typed value hw/block/nvme: fix uint16_t use of uint32_t sgls member hw/block/nvme: fix null ns in register namespace qcow2: Document and enforce the QCowL2Meta invariants block: Move bdrv_drain_all_end_quiesce() to block_int.h block: Remove unused include Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
