Bug ID: 236530
Summary: [FUSE] most fuse syscalls should be interruptible
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
A FUSE filesystem daemon runs in userland and is allowed to do very slow stuff,
like access the network, for any operation. Accordingly, any syscall that
waits on a response from the daemon should be interruptible, so any
unresponsive daemon won't cause a system hang.
The FUSE protocol includes a mechanism for interrupting operations. It's
described in detail in doc/kernel.txt within the libfuse sources. Our driver
currently doesn't implement it, but it should.
