Changes in this patch: - Rework the SCSI pass-through code such that for kernel versions >= 2.6.30 the scst_exec_req_fifo patch is no longer needed. - Modify the pass-through code such that blk_rq_append_bio() is only called for kernel version 2.6.30. For later kernel versions blk_make_request() is called instead. - Rework scst_scsi_exec_async(). - Add debug tracing of SCSI pass-through result status. - Add a lockdep_assert_held() call in scsi_end_async(). git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@5979 d57e44dd-8a1f-0410-8b47-8ef2f437770f

# The recommended way to use this script is as follows:
|
|
# - Create an additional user, e.g. builder
|
|
# - Add a line to the sudoers file that allows that user to invoke yum and
|
|
# yum-builddep. One way to do that is by invoking the following shell
|
|
# commands as root:
|
|
# useradd builder
|
|
# echo 'builder ALL=(ALL) NOPASSWD: /usr/bin/yum, /usr/bin/yum-builddep' >>/etc/sudoers
|
|
# visudo -sc
