Subject: [QUESTION] How to enlarge the max write pages of fuse request
Date: Sun, 8 Mar 2020 23:45:44 +0800	[thread overview]
Message-ID: <5E651328.4090305@huawei.com> (raw)

Hi Miklos,

I want to enlarge the fuse request's bufsize from 128K to 1MB for more
bandwidth as follows, but it does not work.

1. In libfuse, setting fuse_init_out:
outarg->max_write = 1024 * 1024; // 1MB
outarg->max_pages = 256; // 1MB

2. In kernel, fuse_send_write just handle 4B once a time, and failed at
last despite 'req->max_pages' is already set to 256. I wonder if some
more adaption needed or I just went the wrong way? Looking forward to
your rely.

Thanks,
Jun
