This is probably wrong but lets us build the driver with
CONFIG_UIDGID_STRICT_TYPE_CHECKS enabled. Without it, we get
these errors:
drivers/staging/android/logger.c: In function 'logger_read':
drivers/staging/android/logger.c:316:4: error: incompatible type for argument 3
of 'get_next_entry_by_uid'
drivers/staging/android/logger.c:244:15: note: expected 'uid_t' but argument is
of type 'kuid_t'
drivers/staging/android/logger.c: In function 'logger_aio_write':
drivers/staging/android/logger.c:483:14: error: incompatible types when
assigning to type 'uid_t' from type 'kuid_t'
which tells us that the driver is not compatible with user namespaces.
