Subject: fix issue seen on 34f5b82ed231ecce .
X-Git-Tag: v3.22.2~80
X-Git-Url: http://info.iut-bm.univ-fcomte.fr/pub/gitweb/simgrid.git/commitdiff_plain/fa0fb4079f99cf9ceda4ea3537b05f0723e48d29

fix issue seen on 34f5b82ed231ecce .
We were writing inside an existing file, reducing its size for the fs.
And then used_size was becoming <0, which for an unsigned is quite large.
This seems to point to another issue in storage, as used_size might not be initialized properly
