Subject: xfs: set the btree cursor bc_ops in xfs_btree_alloc_cursor
X-Git-Tag: v6.9.0~18^2~81
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c75cc5dc50ffa50f7697afc538a42ae978ce25c4;p=thirdparty%2Fxfsprogs-dev.git

xfs: set the btree cursor bc_ops in xfs_btree_alloc_cursor

Source kernel commit: 056d22c87132cf4968f5e702116439bea9795930

This is a precursor to putting more static data in the btree ops structure.
