Subject: [S390] incorrect reipl nss name.
X-Git-Tag: v2.6.25-rc5~28^2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=583b33bc83d24791f11e862290ee0b79d804d2d8;p=linux-2.6

[S390] incorrect reipl nss name.

/sys/firmware/reipl/nss/name contains the nss name when defsys or
savesys command has been executed. If the defsys or savesys command
fails the kernel_nss_name has to be cleared since a reipl on that
nss name won't be possible.
