SubjectRe: [patch V2 0/7] fs: Substitute bit-spinlocks for PREEMPT_RT and debugging
Hi Thomas,

did you look into killing bіt spinlocks as a public API instead?

The main users seems to be buffer heads, which are so bloated that
an extra spinlock doesn't really matter anyway.

The list_bl and rhashtable uses kinda make sense to be, but they are
pretty nicely abstracted away anyway. The remaining users look
pretty questionable to start with.
