Subject: s3/lib: add is_gmt_token()
X-Git-Tag: samba-4.11.10~20
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3d60f8ac9fa2440fa559fd72f86adc53268254da;p=thirdparty%2Fsamba.git

s3/lib: add is_gmt_token()

This is not present in master as master has been converted to use struct
smb_filename.twrp instead of @GMT string tokens as part of the path.
