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.

I can still see this issue in RHEL-8.6.0-20220312.3-x86_64-dvd1.iso

[root@shshang-rhel8 ~]# rm -rf sa.new ; strace -fttT -o sadc.trc /usr/lib64/sa/sadc -F -L 1 2 sa.new ; grep mtab sadc.trc
16188 16:55:16.100156 openat(AT_FDCWD, "/etc/mtab", O_RDONLY) = 3 <0.000079>
[root@shshang-rhel8 ~]# uname -r

[root@shshang-rhel8 ~]# rpm -q sysstat

Comment 11 Frantisek Sumsal 2022-03-14 10:33:14 UTC 
IIUC, reading /etc/mtab is fine, the original issue is about calling statfs() on the autofs handle, thus triggering the auto mount. CC'ing @msekleta for confirmation.
Comment 12 Frank Liang 2022-04-22 03:23:11 UTC 
Here is test result from RHEL-9 and I do not find 1670060 changed the pass criteria.
I am adding needinfo to Michal.

[root@localhost ~]# uname -r
5.14.0-75.el9.x86_64
[root@localhost ~]# rm -rf sa.new ; strace -fttT -o sadc.trc /usr/lib64/sa/sadc -F -L 1 2 sa.new ; grep mtab sadc.trc
[root@localhost ~]# echo $?

As mentioned previously reading mtab in of itself is not a problem. Issue was calling statvfs() on autofs filesystems which caused them to automount. This is now fixed and RHEL-9 contains this fix as well.
