+Subject: [PATCH] lscpu: Use 4K buffer size instead of BUFSIZ
+
+Some lines in /proc/cpuinfo can be large e.g. flags and can then
+truncate them in displaying them
+
+BUFSIZ can vary quite a bit e.g. glibc/linux systems its 8192
+but on musl/linux and OSX its 1024, on mingW it is 256, some tests e.g.
+x86_64-64cpu-linux6.2.tar.gz has added really long line for cpu flags
+line which is greater than 1024 characters and hence this test fails
+on musl because lscpu -s reports truncated string
+
+Upstream-Status: Submitted [https://github.com/util-linux/util-linux/pull/2492]
