Incremental upgrades of the kernel are distributed as:
A.
patches.
B.
fixes.
C.
hotfixes.
D.
service packs.
Explanation:
Incremental upgrades of the kernel are distributed as patches. For example, if you have version 1.1.45, and you notice that there’s a `patch46.gz’ out there for it, it
means you can upgrade to version 1.1.46 through application of the patch. You might want to make a backup of the source tree first (`make clean’ and then `cd /
usr/src; tar zcvf old-tree.tar.gz linux’ will make a compressed tar archive for you.).
