[PATCH 1/6] libiscsi: disable bh in and abort handler.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Mike Christie <michaelc@xxxxxxxxxxx>

The session lock can be held in the scsi eh thread or the completion
paths run from the net softirq. This disables bhs in iscsi_eh_abort when
taking the session lock.

Patch was made over scsi-rc-fixes.
