Wherever possible, WINE converts Windows API calls to Linux ones, but 
sometimes, there is no matching Linux API. If there isn't, García said, 
/"Wine needs to implement the missing parts. This can result in 
overhead, and it's not always easily solvable in userspace. Solution: 
new Linux features to fill in the missing gaps."/

One recent example is the new |futex_waitv()| 
<https://docs.kernel.org/userspace-api/futex2.html> call in kernel 5.16, 
which brings a new API to Linux that's like Win32's 
|WaitForMultipleObjects()| 
<https://learn.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-waitformultipleobjects> 
call, as this Collabora blog post 
<https://www.collabora.com/news-and-blog/blog/2023/02/17/the-futex-waitv-syscall-gaming-on-linux/> 
explains in depth. Another patch 
<https://lore.kernel.org/all/20190719000322.106163-3-drosen@google.com/> 
brings /optional/ case-insensitivity <https://lwn.net/Articles/784041/> 
to the F2FS, the Flash-friendly file system 
<https://docs.kernel.org/filesystems/f2fs.html>. As another example, 
Valve and its partners are also working on more reliable user-space 
spinlocks <https://lwn.net/Articles/931789/>.
