* Remove the restserver & storageLib initializations These are removed because the storage daemon would handle them. * Remove the linking to restserver and storagelib * Remove call to restserver api. * tgt is now linked to all required c++ libs folly, fbthrift, hyc libs, etc. hyc client apis now replaces the earlier lib api calls. though they are just passing compilation. Proper integration needs to be done. * Call HycStorInitialize() * Moved eventfd_read() inside loop Signed-off-by: Rohan Puri <rohan.puri@primaryio.com> Signed-off-by: Prasad Joshi <Prasad.Joshi@primaryio.com>

So adding retry at TGT for deleting target. Signed-off-by: Shrihari Rathod <shrihari.rathod@primaryio.com> * reqid error handling in cleaner way * Adding other cleanup calls during target delete - 'unbind' and 'conn --op delete' functions were missing in current target delete implementation.

Redesign stord client code Intgration with new Hyc code avoid epoll_wait() and epoll_ctl() calls Signed-off-by: Prasad Joshi <Prasad.Joshi@primaryio.com>
In eventfd handler, we query the list of all struct scsi_cmds which are complete. For each complete scsi_cmd, we call target_cmd_io_done() function. target_cmd_io_done() add scsi_cmd into a completion list, and then adds EPOLLOUT epoll event. In EPOLLOUT event handler, TGTD sends scsi_cmd response back. We avoid EPOLLOUT, by sending the scsi_cmd responses in eventfd. Signed-off-by: Prasad Joshi <Prasad.Joshi@primaryio.com>
