Hello Smita,

I'm working on a small series of enhancement and additions to kernel logs and
trace events in extlog_print() (ELOG). I'm interested to reuse from ELOG the
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
superseded by a different implementation and, furthermore, that this needs to
be reworked because the execution of this code may sleep while in atomic
context.

I'd like to ask if you plan to fix and rebase this series to a current cxl
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
notice that I'd be glad to help by making the necessary changes and by porting
your code to a current cxl branch (of course, retaining your authorship).

Thanks,

Fabio M. De Francesco

Sorry missed your message on my inbox. Yes, I will get back working on v3 on this early next week. Couldn't get a chance to continue due to other pcie work. Hopefully, I can get something out next week.

Thanks
Smita
