Subject: binderfs: use __u32 for device numbers
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7d0174065f4903fb0ce0bab3d5047284faa7226d;p=linux.git

binderfs: use __u32 for device numbers

We allow more then 255 binderfs binder devices to be created since there
are workloads that require more than that. If we use __u8 we'll overflow
after 255. So let's use a __u32.
Note that there's no released kernel with binderfs out there so this is
not a regression.
