Since Arne Redlich was nice enough to fix r223 so that r224 now again compiles on the ReadyNAS, here we go with the lastest release of the iSCSI target for ReadyNAS. From the changelog:

Unit Attention support

UA infrastructure + generation of "power-on, reset or bus-device reset occurred"
UA on session startup / device reset.

Based on the UA patch from Xie Gang <xiegang112@gmail.com>

• fix size of iscsi_cmnd->sense_buffer (introduced with r220),
• whitespace cleanups
