Subject: Update return value of "set" operations
X-Git-Tag: v0.7.0~3
X-Git-Url: https://git.lttng.org/?a=commitdiff_plain;h=3daae22a68a6e74c99d39a8c6b628f5c9121c54a;hp=3daae22a68a6e74c99d39a8c6b628f5c9121c54a;p=urcu.git

Update return value of "set" operations

To follow the way the Linux kernel implements atomic_set(), we change
some API functions so they don't return any value anymore.

This is now the case for:

uatomic_set()
rcu_set_pointer()
rcu_assign_pointer()

This API change is very minor. In all instances of the Linux kernel
using rcu_assign_pointer(), none currently care about its return value.

However, we keep ABI compatibility: rcu_set_pointer_sym() still returns
the "v" value, even though it is not used by its wrapper macro anymore.
