Subject: filemap_sync over-eager at flushing?
Date: Tue, 29 Aug 2000 16:31:15 +0100 (BST) [thread overview]
Message-ID: <200008291531.QAA24159@flint.arm.linux.org.uk> (raw)
Hi,
I've been looking at the TLB/Cache code in 2.4.0-test7 (prompted by
Dave Millers description in test8-pre1), and have come across something
odd:
filemap_sync() calls flush_{cache,tlb}_range(). In between, it
eventually calls filemap_sync_pte(), which uses flush_{cache,tlb}_page().
But hang on, we've already done flush_cache_range(), and are going to do
flush_tlb_range() in filemap_sync(), so isn't the flush_{cache,tlb}_page
rather unnecessary?
