From: James Smart Date: Wed, 25 Apr 2007 13:51:38 +0000 (-0400) Subject: [SCSI] lpfc 8.1.12 : Modify ELS abort handling to prevent double completion X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=07951076aefa4194e1dbf1d8c89eaff040c45155;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [SCSI] lpfc 8.1.12 : Modify ELS abort handling to prevent double completion Modify ELS abort handling to prevent double completion Rework portions of ELS abort handling to prevent double completion - Rework ELS iotags and correct abort routine - Move the (badly wrong) ELS completion logic from the initial ELS abort request function to the ELS completion function. - Fixup the iocb completion handling to account for the ELS abort completions.
