From: Niklas Schnelle Date: Wed, 15 Sep 2021 15:08:44 +0000 (+0200) Subject: s390/pci: add simpler s390dbf traces for events X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6526a597a2e856df9ae94512f9903caccd5196d6;p=linux.git s390/pci: add simpler s390dbf traces for events We often need to figure out what operations were performed in response to an error or availability event. The operations are easily accessible in s390dbf/pci_msg but the events have to be correlated with these from either the kernel log or s390dbf/pci_err. Improve this situation by logging the most important data from error and availability events that is the FID, PEC and FH together with the operations.
