[RFC PATCH 0/2] fuse: Add timeout support for fuse connection

[Yafang Shao <laoar.shao@gmail.com>]

Currently, when an issue arises within the FUSE daemon, the FUSE connection
can become indefinitely stuck. The only resolution currently available is
to manually abort the connection using the sysfs interface. However,
relying solely on the abort interface for automatic error handling is
unreliable. To address this, a timeout mechanism has been introduced in
this series. When the timeout is reached without receiving a response from
the FUSE daemon, the FUSE request will terminate with an error code
returned to the user space, enabling the user space to handle the situation
appropriately.

Furthermore, the timeout value is configurable by the user, allowing for
customization based on specific workload requirements.
