Subject: [PATCH] Fix incorrect usage percentage in Properties dialog for virtual filesystems
X-Git-Tag: archive/raspbian/6.13.0-6+rpi1^2~2
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=d26577ca1de0d00cde39dd6a81f2e0d7da4cc9e0;p=kf6-kio.git

[PATCH] Fix incorrect usage percentage in Properties dialog for virtual filesystems

The Properties dialog for filesystems such as `/proc/` or `/sys/` shows an
incorrect usage percentage (i.e., "-2,147,483,648% used"). This commit fixes
that issue by avoiding a divbyzero: if the `size` variable is `0`, the
`percentUsed` variable is set to `0`.
