Oded Gabbay caa3c8e525 habanalabs: all FD must be closed before removing device ... This patch fixes a bug in the implementation of the function that removes the device. The bug can happen when the device is removed but not the driver itself (e.g. remove by the OS due to PCI freeze in Power architecture). In that case, there maybe open users that are calling IOCTLs while the device is removed. This is a possible race condition that the driver must handle. Otherwise, a kernel panic may occur. This race is prevented in the hard-reset flow, because the driver makes sure the users are closed before continuing with the hard-reset. This race can not occur when the driver itself is removed because the OS makes sure all the file descriptors are closed. The fix is to make sure the open users close their file descriptors and if they don't (after a certain amount of time), the driver sends them a SIGKILL, because the remove of the device can't be stopped. The patch re-uses the same code that is called from the hard-reset flow. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>		2019-04-06 13:23:54 +03:00
