| 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 |
