Subject: xfs_db: set b_ops to NULL in set_cur for types without verifiers
X-Git-Tag: v5.8.0~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2cf166bca8a239271ea6386f8eeea1551fef0e50;p=thirdparty%2Fxfsprogs-dev.git

xfs_db: set b_ops to NULL in set_cur for types without verifiers

If we are using set_cur() to set a type that has no verifier ops,
be sure to set b_ops to NULL so that the old verifiers don't run
against the buffer anymore, which may have changed size.
