Subject: [CIFS] Explicitly set stat->blksize
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5fe14c851efedf95b0e7652a3a7b93ec899d1599;p=linux-beck.git

[CIFS] Explicitly set stat->blksize

CIFS may perform I/O over the network in larger chunks than the page size,
so it should explicitly set stat->blksize to ensure optimal I/O bandwidth
