From 253f4911f297b83745938b7f2c5649b94730b002 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 6 Apr 2016 09:19:55 +1000 Subject: xfs: better xfs_trans_alloc interface Merge xfs_trans_reserve and xfs_trans_alloc into a single function call that returns a transaction with all the required log and block reservations, and which allows passing transaction flags directly to avoid the cumbersome _xfs_trans_alloc interface. While we're at it we also get rid of the transaction type argument that has been superflous since we stopped supporting the non-CIL logging mode. The guts of it will be removed in another patch.
