+Subject: [PATCH 288/323] net: xfrm: Use sequence counter with associated
+ spinlock
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+A sequence counter write section must be serialized or its internal
+state can get corrupted. A plain seqcount_t does not contain the
+information of which lock must be held to guaranteee write side
+serialization.
+
+For xfrm_state_hash_generation, use seqcount_spinlock_t instead of plain
+seqcount_t.  This allows to associate the spinlock used for write
+serialization with the sequence counter. It thus enables lockdep to
+verify that the write serialization lock is indeed held before entering
+the sequence counter write section.
+
+If lockdep is disabled, this lock association is compiled out and has
+neither storage size nor runtime overhead.
