LOR so_snd_sx @ uipc_sockbuf.c and filedesc structure @ uipc_usrreq.c

[Yuri Pankov]

Hi,

Getting this LOR every time I login via ssh after reboot, and it doesn't
seem to be reported previously. Running 10.0-CURRENT r230537.

lock order reversal:
 1st 0xfffffe0160615490 so_snd_sx (so_snd_sx) @ /usr/src/sys/kern/uipc_sockbuf.c:148
 2nd 0xfffffe0029ef1048 filedesc structure (filedesc structure) @ /usr/src/sys/kern/uipc_usrreq.c:1872
