Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Description Josef Ridky 2019-04-12 09:27:59 UTC 
Description of problem:

Output of free utility for Memory used is wrong.
Now, the value is decreased by integer from /proc/meminfo -> Slab, but based on upstream version, it should be decreased only by integer from /proc/meminfo -> SReclaimable.

Version-Release number of selected component (if applicable):
procps-ng-3.3.10-23.el7

How reproducible:
$ free 

Actual results:
Mem used is computed without SUnreclaim.

Expected results:
Mem used should contain value from SUnreclaim

Additional info:
This bug is blocking #1250060 (net-snmp)
Comment 1 Jan Rybar 2019-04-12 11:20:57 UTC 
Unreclaimable slabs shouldn't be counted in available memory.
Josef, thanks for the catch!
