Subject[PATCH v2 01/19] fscache: export fscache_end_operation()
From
Date
From: Jeffle Xu <jefflexu@linux.alibaba.com>

Export fscache_end_operation() to avoid code duplication.

Besides, considering the paired fscache_begin_read_operation() is
already exported, it shall make sense to also export
fscache_end_operation().
