RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
There is a questionable KConfig option called CONFIG_CIFS_EXPERIMENTAL that has been used over the years upstream to merge questionable and broken code into cifs. I've begun a push upstream to rip that KConfig option out along with any broken code under it. One of the broken things is the export ops code which was merged as stubs in 2007 and never finished.
The maintainer is so far reticent to rip this code out, even though it's broken, So I may just settle for moving the "good" things out from under that setting and turning the rest of it off so it won't be compiled in.
Opening this bug to track that cleanup work upstream and for RHEL6.

Hi jeff,
I checked source code, find something about 'lease' and 'cifs_acl'. When I test 'lease' in cifs, that failed (NFS too), could you pls explain the relationship of these patches and 'lease' or some feature?
Did you mean the "localleases" mount option? That has been moved out from under the EXPERIMENTAL tag in this commit:

[fs] cifs: move "ntlmssp" and "local_leases" options out of experimental code
The "cifsacl" option was also moved out of the EXPERIMENTAL tag and that option was enabled for RHEL6.
