Brian Behlendorf 2b7ab9d4d9 Linux 2.6.26 compat, lookup_bdev() ... It's doubtful many people were impacted by this but commit 6c28567 accidentally broke ZFS builds for 2.6.26 and earlier kernels. This commit depends on the lookup_bdev() function which exists in 2.6.26 but wasn't exported until 2.6.27. The availability of the function isn't critical so a wrapper is introduced which returns ERR_PTR(-ENOTSUP) when the function isn't defined. This will have the effect of causing zvol_is_zvol() to always fail for 2.6.26 kernels. This in turn means vdevs will always get opened concurrently which is good for normal usage. This will only become an issue if your using a zvol as a vdev in another pool. In which case you really should be using a newer kernel anyway.
