Re: [PATCH V2 0/2] md/raid10: annotate lockless access and fix hungtask

在 2026/8/17 11:33, Zizhi Wo 写道:

Patch 1 annotates the lockless access to conf->array_freeze_pending with
READ_ONCE()/WRITE_ONCE(). No functional change.

Patch 2 fixes a hungtask in raid10.

Changes in v2:
- Add patch 1 to annotate the lockless reads of conf->array_freeze_pending
   with READ_ONCE(), paried with WRITE_ONCE() on the write side.
- Use READ_ONCE() when reading conf->array_freeze_pending in patch 2.

v1:
