Subject: linux-next: build failure after merge of the bcachefs tree
Hi all,
After merging the fs-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit
87a3e08121cb ("bcachefs: Switch to memalloc_flags_do() for vmalloc allocations")
from the bcachefs tree interacting with commit
0df1d8edfe8a ("Revert "mm: introduce PF_MEMALLOC_NORECLAIM, PF_MEMALLOC_NOWARN"")
from the mm-hotfixes-unstable branch of the mm-hotfixes tree.
I have reverted that mm-hotfixes commit for today.
