Subject: fuser: increase mpoint length of for octal escape
X-Git-Tag: v23.0rc1~19
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e7aeecb644957559be0ad6f8bf8398814f1c3ec9;p=psmisc

fuser: increase mpoint length of for octal escape

The mount point is set to PATH_MAX but if octal escaping is used
then it will exceed this limit.

Fixes rhbz#1078887 (no url, its a restricted access bug)
