Subject: perf ui scripts: Switch FILENAME_MAX to NAME_MAX
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=008b75759eb98fa6ee83eae8e9e19722121de633;p=users%2Fjedix%2Flinux-maple.git

perf ui scripts: Switch FILENAME_MAX to NAME_MAX

FILENAME_MAX is the same as PATH_MAX (4kb) in glibc rather than
NAME_MAX's 255. Switch to using NAME_MAX and ensure the '\0' is
accounted for in the path's buffer size.
