| H A D | loop.c | 498ef5c7 Wed Mar 30 00:29:14 CDT 2022 Christoph Hellwig <hch@lst.de> loop: suppress uevents while reconfiguring the device
Currently, udev change event is generated for a loop device before the
device is ready for IO. Due to serialization on lo->lo_mutex in
lo_open() this does not matter because anybody is able to open the
device and do IO only after the configuration is finished. However this
synchronization in lo_open() is going away so make sure userspace
reacting to the change event will see the new device state by generating
the event only when the device is setup.
