Arnaldo Carvalho de Melo fd1f70776a tools lib api: Fix mount_overload() snprintf truncation and toupper range ... mount_overload() builds an environment variable name like "PERF_SYSFS_ENVIRONMENT" from fs->name. Two bugs: 1) snprintf() uses name_len as the buffer size instead of sizeof(upper_name). For fs->name = "sysfs" (len=5), the output is truncated to "PERF" (4 chars + null), so getenv() never finds the intended variable. 2) mem_toupper() only uppercases name_len bytes, converting just the "PERF" prefix rather than the full string including the filesystem name portion. Fix by using sizeof(upper_name) for snprintf and strlen(upper_name) for mem_toupper, so the full "PERF_SYSFS_ENVIRONMENT" string is correctly formatted and uppercased.
