Subject: [PATCH] bcache-tools: bcache-export-cached doesn't match backing device w/ offset, features
Date: Tue, 11 May 2021 15:06:12 -0400 [thread overview]
Message-ID: <CAH6h+he=rxPq9E8zmenmLp9vc9X4D1-6OQqVm0XyeMei3uLgqg@mail.gmail.com> (raw)
updated the awk snippet used in 'bcache-export-cached' so it matches the three
current superblock versions of a "backing" device (BCACHE_SB_VERSION_BDEV,
BCACHE_SB_VERSION_BDEV_WITH_OFFSET, BCACHE_SB_VERSION_BDEV_WITH_FEATURES)
