Subject: dma-buf: don't open-code atomic_long_read()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a1f6dbac629e36f89a1332b5ae773b831c136ee9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dma-buf: don't open-code atomic_long_read()

... not to mention that even atomic_long_read() is too low-level here -
there's file_count().
