Description :
The kernel meta package

Update Information:

The 5.16.15 stable kernel update includes a number of important fixes across the
tree. It also includes a temporary revert of the feature that makes QNAP NFS
mounts fail. We will carry this revert through the 5.16 series in attempt to
give the vendor more time to come out with an update, or upstream to come out
with a solution.
