But both 13.2 and 14.1 versions s= till don't wait for confirmation (neither for the read to end or that INTERRUPT = was received), they just sent RELEASE. As was stated before, MooseFS has reference counters anyway, so it handles = the interrupts correctly anyway. Other filesystems using FUSE may not, and if t= hat is the case, their read operations, that get interrupted, may behave unexpectedly (and even end with a segfault). Since Linux kernel waits for t= he read to finish, those filesystems will behave differently there. Linux and FreeBSD are two main systems that implement FUSE, so we kind of feel oblige= d to point this out to you, that's why this thread was first created. But it's = not a direct issue for our filesystem, if that is what you are asking. --=20 You are receiving this mail because: You are the assignee for the bug.=
