Subject: scsi,rcu: Convert call_rcu(fc_rport_free_rcu) to kfree_rcu()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8497a24a43374f0142335b0ef0614ccc459e3d8d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

scsi,rcu: Convert call_rcu(fc_rport_free_rcu) to kfree_rcu()

The rcu callback fc_rport_free_rcu() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(fc_rport_free_rcu).
