To be sure Linus is aware of the pending revert before releasing -rc7,
let me add this to the list of tracked regressions:

#regzbot ^introduced f95bdb700bc6bb74e1199b1f5f90c613e152cfa7.
#regzbot title mm: problems with the SRCU changeover (two reverts pending)
#regzbot monitor:
https://lore.kernel.org/all/ZH6K0McWBeCjaf16@xxxxxxxxxxxxxxxxxxx/
#regzbot fix: Revert "mm: vmscan: make global slab shrink lockless"
#regzbot ignore-activity

Side note: "Revert "mm: vmscan: add shrinker_srcu_generation"" (also in
mm-hotfixes-unstable/next) is related. See
https://lore.kernel.org/all/51cbf269-daff-d7b8-653f-7ba388475ab8@xxxxxxxxx/

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
