Subject: setlocalversion: add -e option
X-Git-Tag: ceph-for-6.13-rc4~108^2~21
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=e2ff1219a5541a22921016219c4d86a6d0190d15;p=ceph-client.git

setlocalversion: add -e option

Set the -e option to ensure this script fails on any unexpected errors.

Without this change, the kernel build may continue running with an
incorrect string in include/config/kernel.release.

Currently, try_tag() returns 1 when the expected tag is not found as an
ancestor, but this is a case where the script should continue.
