From 0e0b494ca8c54a7297d0cc549405091019b3b77e Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Sun, 23 Jan 2011 09:42:50 -0600 Subject: libata: separate error handler into usable components Right at the moment, the libata error handler is incredibly monolithic. This makes it impossible to use from composite drivers like libsas and ipr which have to handle error themselves in the first instance. The essence of the change is to split the monolithic error handler into two components: one which handles a queue of ata commands for processing and the other which handles the back end of readying a port. This allows the upper error handler fine grained control in calling libsas functions (and making sure they only get called for ATA commands whose lower errors have been fixed up).
