However internally the ioctl flag is not required to delete all the unmounted devices. Instead leave btrfs_ioctl_vol_args::name NULL. v6: Use the changed fn name btrfs_free_stale_devices(). Change in title: Old v5: Cover-letter: [PATCH v5] Add cli and ioctl to ignore a scanned device Kernel: [PATCH v5] btrfs: introduce feature to ignore a btrfs device Progs: [PATCH v5] btrfs-progs: add 'btrfs device ignore' cli v5: Adds feature to delete all stale devices Reuses btrfs_free_stale_devices() fn and so depends on the patch-set [1] in the ML. Uses struct btrfs_ioctl_vol_args_v2 instead of struct btrfs_ioctl_vol_args as arg Does the device path matching instead of btrfs_device matching (we won't delete the mounted device as btrfs_free_stale_devices() checks for it) v4: No change. But as the ML thread may be confusing, so resend. v3: No change. Send to correct ML. v2: Accepts review from Nikolay, details are in the specific patch. Patch 1/2 is renamed from [PATCH 1/2] btrfs: refactor btrfs_free_stale_device() to get device list delete to [PATCH 1/2] btrfs: add function to device list delete Adds cli and ioctl to forget a scanned device or forget all stale devices in the kernel.
