e167e2ebb7 nightly build: Remove kernel version 2.6.30 and older 
Or in other words, focus on RHEL 6 (kernel 2.6.32) and later.

e680de4602 fcst: Remove ft_cmd_dump() and ft_cmd_tm_dump() 
Functions that dump the state of SCSI commands and task management functions
should occur in the SCST core instead of in target drivers. If anyone needs
this functionality it should be moved into the SCST core.

08e532715d Remove procfs support 
Since all RHEL/CentOS 5 users have upgraded to a newer version, procfs
support is no longer necessary. Hence remove procfs support. This patch
has been generated as follows:

git grep -lw CONFIG_SCST_PROC iscsi-scst qla2x00t scst scst_local srpt |\
  while read f; do
    echo ${f}
    unifdef -U CONFIG_SCST_PROC ${f} >${f}.out
    mv ${f}.out ${f}
  done

followed by two small manual edits in scst/include/scst.h and also in
qla2x00t/qla2x00-target/qla2x00t.c.
