QStorageInfo/Unix: exclude invalid volumes from mountedVolumes()
Invalid are usually those mounted on a filesystem we can't access: $ df /run/user/0/gvfs df: /run/user/0/gvfs: Permission denied $ ./qstorageinfo /run/user/0/gvfs Could not get info on /run/user/0/gvfs df already doesn't include it by default: $ df | grep -c gvfs 0 But we were: $./qstorageinfo | sed -n '1p;/gvfs/p' Filesystem (Type) Size Available BSize Label Mounted on gvfsd-fuse (fuse.gvfsd-fuse) RW 0 0 0 /run/user/0/gvfs Note also how this is showing a total size of 0, which is usually the type of filesystem we exclude. It's actually -1 but got rounded down to 0 when we divided by 1024. Pick-to: 6.6 Change-Id: I8f3ce163ccc5408cac39fffd178d7e4f9dc13b24 Reviewed-by: Edward Welbourne <edward.welbourne@qt.io> Reviewed-by: Ahmad Samir <a.samirh78@gmail.com>
