In general, Linus tries to avoid breaking userspace.
But you have not explained which version of BLFS you are going to
build on your LFS-7.2. Much of 7.6 and current svn has not been
tested on older versions of LFS. Certainly, when I updated versions
of _firefox_ on old systems I had problems in the LFS-7.0/7.1 area
("problematic" gcc versions).
As a general rule: update to a current LTS kernel. Recent 3.14
seems good. But (depending on *which* BLFS version you are
building), check the packages in BLFS to see which kernel options
you will need.
