[PATCH blktests v2 02/11] common/xfs: Create common helper to check for XFS support

From: Logan Gunthorpe
Date: Wed Sep 30 2020 - 14:54:33 EST


Two nvme tests create and mount XFS filesystems and check for mkfs.xfs.

They should also check for XFS support in the kernel so create a common
helper for this.
