Linus Torvalds c06944560a 20 hotfixes. 7 are cc:stable and the remainder address post-6.15 issues
or aren't considered necessary for -stable kernels.  Only 4 are for MM.
 
 - The 3 patch series `Revert "bcache: update min_heap_callbacks to use
   default builtin swap"' from Kuan-Wei Chiu backs out the author's recent
   min_heap changes due to a performance regression.  A fix for this
   regression has been developed but we felt it best to go back to the
   known-good version to give the new code more bake time.
 
 - A lot of MAINTAINERS maintenance.  I like to get these changes
   upstreamed promptly because they can't break things and more
   accurate/complete MAINTAINERS info hopefully improves the speed and
   accuracy of our responses to submitters and reporters.
