smb3: add dynamic tracepoints for shutdown ioctl
For debugging an umount failure in xfstests generic/043 generic/044 in some configurations, we needed more information on the shutdown ioctl which was suspected of being related to the cause, so tracepoints are added in this patch e.g. "trace-cmd record -e smb3_shutdown_enter -e smb3_shutdown_done -e smb3_shutdown_err" Sample output: godown-47084 [011] ..... 3313.756965: smb3_shutdown_enter: flags=0x1 tid=0x733b3e75 godown-47084 [011] ..... 3313.756968: smb3_shutdown_done: flags=0x1 tid=0x733b3e75 Tested-by: Anthony Nandaa (Microsoft) <[email protected]> Signed-off-by: Steve French <[email protected]>
