In case anyone has any comments/corrections/suggestions.... I did a full backport of all cifs changesets through 5.18-rc4 onto 5.15. This may help those running older kernels who want something closer to mainline rather than just the much smaller number of fixes that go into 5.15 stable See https://git.samba.org/?p=sfrench/cifs-2.6.git;a=shortlog;h=refs/heads/5.15-backport I did run the buildbot regression tests on it, but if anyone sees any problems with it let me know. -- Thanks, Steve
