X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b9ca67b2ddf021491a3741d9555e8ff59b2175ba;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

fuse: fix lock annotations

Sparse doesn't understand lock annotations of the form
__releases(&foo->lock).  Change them to __releases(foo->lock).  Same
for __acquires().
