This will avoid mistaking the word "filters" with the lvm.conf filter setting. --- lib/device/device_id.c | 6 +++--- lib/label/label.c | 4 ++-- tools/lvmdevices.c | 4 ++-- tools/pvscan.c | 4 ++-- tools/vgimportclone.c | 4 ++-- 5 files changed, 11 insertions(+), 11 deletions(-) diff --git a/lib/device/device_id.c b/lib/device/device_id.c index fa71874d0..0f7c42f79 100644 --- a/lib/device/device_id.c +++ b/lib/device/device_id.c @@ -1777,7 +1777,7 @@ void device_ids_validate(struct cmd_context *cmd, struct dm_list *scanned_devs, * probably wants to do something about it. */ if (!cmd->filter->passes_filter(cmd, cmd->filter, dev, "persistent")) { - log_warn("Devices file %s is excluded by filter: %s.", + log_warn("Devices file %s is excluded: %s.", dev_name(dev), dev_filtered_reason(dev)); continue; } @@ -1863,7 +1863,7 @@ void device_ids_validate(struct cmd_context *cmd, struct dm_list *scanned_devs, continue; if (!cmd->filter->passes_filter(cmd, cmd->filter, dev, "persistent")) { - log_warn("Devices file %s is excluded by filter: %s.", + log_warn("Devices file %s is excluded: %s.", dev_name(dev), dev_filtered_reason(dev)); /* FIXME: what if this dev is wrongly matched and should be checked below?
