* doc: update fuse interrupt documentationCsaba Henk2020-07-201-8/+89
| | | | | | | | | | | | | | | | | | | | As Issue #1310 pointed out, for fops that have interrupt handlers the fop handler needs to pay attention to give the proper FUSE response when it's interrupted. This change extends the interrupt documentation with guidelines regarding the FUSE response. Also: - improve wording - add an 'Overview' section to explain the code flow before going in to the technical details Change-Id: I852bfb717b1bde73f220878d6376429564413820 updates: #1374 Signed-off-by: Csaba Henk <csaba@redhat.com>
* fuse: diagnostic FLUSH interruptCsaba Henk2018-11-061-0/+130
We add dummy interrupt handling for the FLUSH fuse message. It can be enabled by the "--fuse-flush-handle-interrupt" hidden command line option, or "-ofuse-flush-handle-interrupt=yes" mount option. It serves no other than diagnostic & demonstational purposes -- to exercise the interrupt handling framework a bit and to give an usage example. Documentation is also provided that showcases interrupt handling via FLUSH. Change-Id: I522f1e798501d06b74ac3592a5f73c1ab0590c60 updates: #465 Signed-off-by: Csaba Henk <csaba@redhat.com>
