Hi,

Since patch #7 and #8 from the series:

   [PATCH v1 00/25] seqlock: Extend seqcount API with associated locks
   https://lore.kernel.org/lkml/20200519214547.352050-1-a.darwish@linutronix.de

are now pending on the lockdep/x86 IRQ state tracking patch series:

   [PATCH 00/14] x86/entry: disallow #DB more and x86/entry lockdep/nmi
   https://lkml.kernel.org/r/20200529212728.795169701@infradead.org

   [PATCH v3 0/5] lockdep: Change IRQ state tracking to use per-cpu variables
   https://lkml.kernel.org/r/20200529213550.683440625@infradead.org

This is a repost only of the seqcount_t call sites bugfixes that were on
top of the seqlock patch series.

These fixes are independent, and can thus be merged on their own. I'm
reposting them now so they can at least hit -rc2 or -rc3.

Changelog-v2:

  - patch #1: Add a missing up_read() on netdev_get_name() error path
              exit. Thanks to Dan/kbuild-bot report.

  - patch #4: new patch, invalid preemptible context found by the new
              lockdep checks added in the seqlock series + kbuild-bot.

Thanks,

8<--------------
