Kernel version v2.6.38-rc2 is affected.
This patch fixes silly debug print bug in nfs4_remote_referral_mount() (maybe
somewhere else too):
"dprintk("--> nfs4_referral_get_sb()\n");"
was printed instead of
"dprintk("--> nfs4_remote_referral_mount()\n");"
It also reduces code size by replacing all this function names in debug prints
containing "<--" or "-->" to "%s" specifier and "__func__" argument.
Replace done by sed with following regexp:
sed -i 's@\(.*<\?-->\? \+\)[^%,(,\]\+\(.\+"\)@\1%s\2, __func__@g' fs/nfs/*.c
