[PATCH RFC 01/11] um: Make UBD requests synchronous in TT ext/infcpu mode

2023-11-03 Thread Benjamin Beichler
The UBD driver employs multiple threads to enhance block device accesses in userspace. These threads communicate via pipes and are triggered by interrupts that utilize the SIGIO handler. However, in TT mode, both inf-cpu and external modes, this asynchronous, multithreaded request processing lead
