This adds a kernel-level performance profiler for the VFS. By enabling CONFIG_FS_PROFILER, the core VFS system calls (file_read, file_write, file_open, and file_close) are instrumented to track high-resolution execution times using clock_systime_timespec() seamlessly. The collected statistics are exposed dynamically via a new procfs node at /proc/fs/profile, allowing CI regression testing without needing external debugging tools.
