I would like to know when to use SRCPV and SRCREV, while working with recipes that fetch from git repositories.

The weird thing is if I try to use SRCREV to append to the PV, it adds gitAUTOINC to the folder name , which is very weird. 

SRCREV = "a5556fb251253ccb674bd22d9703c37f6f8807a8"

SRC_URI = "git://git.xilinx.com/linux-xlnx.git;protocol=git;branch=${KBRANCH} \
           file://defconfig"

LINUX_VERSION = "2.6.37"

PR = "r17"
-PV = "${LINUX_VERSION}+git${SRCPV}"
+PV = "${LINUX_VERSION}+git${SRCREV}"

NOTE: package linux-xilinx-2.6.37+gitAUTOINC-r17: task do_fetch: Started

So, I'm not sure what the correct thing to do is. In the end, the generated package folder name is incorrect because it doesn't correctly reflect the correct commit id , as specified by the SRCREV.
