    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.
