Subject: [PATCHSET] libata: various fixes related to EH
Date: Sun, 22 Jan 2006 16:58:30 +0900 [thread overview]
Message-ID: <11379167103055-git-send-email-htejun@gmail.com> (raw)

Hello, Jeff, Albert.
This patchset is composed of 12 patches fixing/updating various EH
related stuff in libata. Although not all of the patches are
logically related, they need to be ordered because they modify
similar parts of code.
#01 : cosmetic
#02 : ata_qc_new/free model
#03 : ata_qc_issue() error handling fix
#04 : detailed AC_ERR_* flags
#05 : return AC_ERR_* from issue functions
#06-07 : ata_eh_qc_retry/complete
#08-12 : eh synchronization (#12 is the pio/eh sync patch I talked
about in the thread "update timer for PIO polling - revised")
Jeff, these are hopefully more acceptable patches from my recent EH
work. I'll soon follow up with more pervasive patches. My working
version of new EH now does most things described in ATA EH doc
including reset, revalidation and gearing down. I've also ported
Jen's NCQ support over it, and, although it has a few issues, it's
generally working okay.
I think libata really needs better EH and NCQ/hotplug stuff is already
somewhat late. I hope we can go somewhere this time.
Thanks
