[PATCH -next v6] staging: fwserial: Switch to kfree_rcu() API

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Instead of invoking a synchronize_rcu() to free a pointer after a grace
period, we can directly make use of a new API that does the same but in
a more efficient way.

Changelog:
v3: the first version of the PATCH
v1: v3 resent as v1
v2: use kfree_rcu() instead of kvfree_rcu() for clarity
v4: resend v2 as v4 to avoid versioning confusion
v5: add the rcu_head of fwtty_peer as the input param for wider usage
v6: revert to v4
