It's not like it has been staged for the next merge window. It's still
in an RFC state. The changes are not trivial and need further review.
I don't know if it can hit the next merge window. As such, I picked a
long distance for this proposal. If it ends up going upstream sooner, we
can change this document.

If wq_cpu_set option is set, the default thread_pool value will be adjusted accordingly. Signed-off-by: Ammar Faizi <ammarfaizi2@gnuweeb.org> --- Documentation/ch-mount-options.rst | 3 +++ 1 file changed, 3 insertions(+)
