We recommend that all users of Ksplice Uptrack running UEKR6 5.4.17 on
OL7 and OL8 install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y

A race between certain XFS writeback operations can lead to system
crashes and filesystem corruption.

* Avoid excessive compaction on file-backed pinned pages.

An overzealous heuristic to determine if a page can be compacted in the
memory compaction subsystem could lead to downgraded performances on
processes using pinned, file-backed pages.
