Review request for KDE Frameworks.


Bugs: 369275
    https://bugs.kde.org/show_bug.cgi?id=369275


Repository: kio


Description
-------

Currently, KIO uses lstat to get the buffersize for readlink.
But in certain situations, it returns inappropriate value.

For example, "/proc/self" or "/sys/bus/cpu/devices/*" returns its size is 0 , and then readlink fails with EINVAL.(so link won't be shown in kde application.)
TMSU seems it returns its target's actual filesize insted of the link's filesize itself.

This patch changes the buffersize to 1024 bytes if it is 0.
And later truncate it to actual size.
