Subject: [PATCH] 9p: darwin: meson: Allow VirtFS on Darwin
|
|
|
|
To allow VirtFS on darwin, we need to check that pthread_fchdir_np is
|
|
available, which has only been available since macOS 10.12.
|
|
|
|
Additionally, virtfs_proxy_helper is disabled on Darwin. This patch
|
|
series does not currently provide an implementation of the proxy-helper,
|
|
but this functionality could be implemented later on.
