[PATCH 0/6] Initialize device state before userspace registration

[Jiale Yao]

Several drivers register character devices or sysfs attributes before
initializing synchronization objects and related state used by their
userspace entry points. Registration makes those entry points immediately
available, so a concurrent access can reach partially initialized state.

Move each initialization ahead of the corresponding registration. The
patches are independent and cover AoE, fsl-mc, MSHV, IBM VMC, DCSSBLK,
and the RDC321x watchdog.

Jiale Yao (6):
  aoe: initialize error message synchronization before registration
  bus: fsl-mc: initialize UAPI state before device registration
  Drivers: hv: initialize partition table before device registration
  misc: ibmvmc: initialize HMC state before device registration
  s390/dcssblk: initialize device semaphore before sysfs registration
  watchdog: rdc321x: initialize device state before registration
