I'm interested to reuse from ELOG th= e=20 infrastructure which you made to trace the CXL Protocol Errors. I'm aware that this series depends on an old one from Ira which has been=20 superseded by a different implementation and, furthermore, that this needs = to=20 be reworked because the execution of this code may sleep while in atomic= =20 context.=20 I'd like to ask if you plan to fix and rebase this series to a current cxl= =20 branch. If so, I'll wait for the next version to integrate in ELOG. Otherwise, if you are not anymore actively working on this series, please=20 notice that I'd be glad to help by making the necessary changes and by port= ing=20 your code to a current cxl branch (of course, retaining your authorship). Thanks, =46abio M.
