Merge branch 'stmmac-cleanups'
Corentin Labbe says: ==================== net: stmmac: misc fix I am currently working on dwmac-sun8i glue driver for Allwinner H3/A83T/A64. This series is the result of all minor problem found in the stmmac driver. All patch are tested on cubieboard2 via dwmac-sunxi and on pine64/orangepis via dwmac-sun8i. Changes since v1: - Removed netdev_dbg() in "net: stmmac: print phy information" - Removed patch "net: stmmac: Implement NAPI for TX", it will be reworked - Changed error message in "Correct the error message about invalid speed" - Added some acked-by ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

However, conditions at the time of the race are count of PERCPU_COUNT_BIAS + 0 and __PERCPU_REF_DEAD and __PERCPU_REF_ATOMIC set. The fix is to make the tryget routines use an actual boolean internally instead of the atomic long result truncated to a int.
