The patch below fixes the following checkpatch warning: __func__ should be used instead of gcc specific __FUNCTION__ This patch has been tested as follows: - Checked that make iscsi scst still works. - Checked that after loading the scst module the kernel messages generated because of the shell command "echo all >/proc/scsi_tg/trace_level" still make sense. An example: [ 646.408035] [5845]: scst: scst_proc_log_entry_write:346:Changed trace level for "scsi_tgt": old 0x80005f0e, new 0xffffffff - Checked that the patch generated by generate-kernel-patch still applies cleanly to the 2.6.25.4 kernel, that the patched kernel still compiles, installs and boots and that the scst, iscsi-scst and ib_srpt modules still load (I performed rm -rf /lib/modules/2.6.25.4* before starting kernel compilation).
