Subject: 答复: [PATCH v4] fuse: add max_pages option
Date: Wed, 26 Sep 2018 09:39:56 +0000	[thread overview]

Hi Constantine,

I haven't tested the patch yet. But after reviewing the patch, I don't see anything related to BDI_CAP_STRICTLIMIT. So would you please explain a little bit more? Thanks.

PS: I did try increasing FUSE_MAX_PAGES_PER_REQ, but it seemed not helping in my scenario(writeback cache enabled, 4K writes, total write size is not very large).
