Subject: filecount plugin: Fixed an off-by-one error in the configuration code.
X-Git-Tag: collectd-4.5.2~17

filecount plugin: Fixed an off-by-one error in the configuration code.

The memory allocated to store the information about configured directories did
not take into account the newly added directory. This would cause a segfault
at some point of time (when specifying more than four directories in my case).

Thanks to Martin Janota <janota.m@cce.cz> for finding and reporting this bug.
