Block patches for 6.0-rc1:
- Mark the qcow2 cache clean timer as external to fix record/replay - Fix the mirror filter node's permissions so that an external process cannot grab an image while it is used as the mirror source - Add documentation about FUSE exports to the storage daemon - When creating a qcow2 image with the data-file-raw option, all metadata structures should be preallocated - iotest fixes -----BEGIN PGP SIGNATURE----- iQFGBAABCAAwFiEEkb62CjDbPohX0Rgp9AfbAGHVz0AFAmBjG9ASHG1yZWl0ekBy ZWRoYXQuY29tAAoJEPQH2wBh1c9AVa4H/1NC4aTFi2sMzyQ8hkUck2llPiZdxP4V KZbyUay+z2pLPWMonyDP6szGv6444lHGBnGQWKZHcw4o5xWNu50jEB2YpkhXS9i1 8shkZNVGxy6CVxinhrFG9qMv7GuoX3vOsVu5HnBjgpM162ZVYR+Af/8erqG1A4js 9odM5Zl6hb+okbSovgucT3UxNeYvBDnhsKzpQnvUvsdJu3RKz6gSlTz+f6jJLLP/ +hK54CDkCpK4fY6W0QLcZcLmmhTHYZXgeKDAHWGAzBH5p3ARY6uAXGZ9+fLE88X4 fhgcuYeLMS+sJCzGXnEDAmGebGhEOzszvskBRIHdWK861zg0RssWQP4= =BdFo -----END PGP SIGNATURE----- Merge remote-tracking branch 'remotes/maxreitz/tags/pull-block-2021-03-30' into staging Block patches for 6.0-rc1: - Mark the qcow2 cache clean timer as external to fix record/replay - Fix the mirror filter node's permissions so that an external process cannot grab an image while it is used as the mirror source - Add documentation about FUSE exports to the storage daemon - When creating a qcow2 image with the data-file-raw option, all metadata structures should be preallocated - iotest fixes # gpg: Signature made Tue 30 Mar 2021 13:38:40 BST # 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-2021-03-30: iotests/244: Test preallocation for data-file-raw qcow2: Force preallocation with data-file-raw qsd: Document FUSE exports block/mirror: Fix mirror_top's permissions iotests/046: Filter request length qcow2: use external virtual timers iotests/116: Fix reference output iotests: fix 051.out expected output after error text touchups iotests: Fix typo in iotest 051 Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
