Yep. We save the old context, run our loop, and then restore the old
context.

Thanks Daniel. I see it being initialized. But then it is overwritten
from saved_ctx, right?

Hi Daniel,
I could not find where op_ctx gets populated in lru_run_lane(). I'm using
2.5.1.

It should be valid. lru_run_lane() sets up op_ctx, so it should be set
correctly even in the LRU thread case.

It looks like the assert() below and the comment in
mdcache_lru_clean() may not be valid in all cases. For example, if
cache is getting cleaned in the context of the LRU background thread,
the op_ctx will be NULL and the code may get into the 'else' part
(lru_run() -> lru_run_lane() -> _mdcache_lru_unref() ->
mdcache_lru_clean()):
Do any of the calls after the 'if-else' block use 'op_ctx'? If those
don't us 'op_ctx', the 'else' part can be safely removed, right?
if (export_id >= 0 && op_ctx != NULL &&
op_ctx->ctx_export != NULL &&
