Subject: fuse: fix SetPageUptodate() condition in STORE
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=063ec1e595f8a82b5a8fd0acb3e88c8b49a1e6c1;p=linux-beck.git

fuse: fix SetPageUptodate() condition in STORE

As noticed by Coverity the "num != 0" condition never triggers.  Instead it
should check for a complete page.
