damon_reclaim_init() allocates a memory chunk for ctx with damon_new_ctx(). When damon_select_ops() fails, ctx is not released, which will lead to a memory leak.

I realized this issue is also in DAMON_LRU_SORT, so posted a patch: https://lore.kernel.org/damon/20220714170458.49727-1-sj@kernel.org/

I mistakenly forgot CC-ing you, so letting you know here.

Thanks, SJ
