Subject: iscsi-target: Fix processing of OOO commands
From: Shlomo Pongratz <[email protected]>
commit 3eccfdb01da58fbd0f789ae6ca61cee3769e26de upstream.
Fix two issues in OOO commands processing done at iscsit_attach_ooo_cmdsn.
Handle command serial numbers wrap around by using iscsi_sna_lt and not regular
comparisson.
The routine iterates until it finds an entry whose serial number is greater
than the serial number of
the new one, thus the new entry should be inserted before that entry and not
after.
