Subject: [PATCH 5/5] xfs: Refactor xfs_da_state_alloc() helper
Date: Wed, 22 Jul 2020 11:05:18 +0200 [thread overview]
Message-ID: <20200722090518.214624-6-cmaiolino@redhat.com> (raw)
In-Reply-To: <20200722090518.214624-1-cmaiolino@redhat.com>
Every call to xfs_da_state_alloc() also requires setting up state->args
and state->mp
Change xfs_da_state_alloc() to receive an xfs_da_args_t as argument and
return a xfs_da_state_t with both args and mp already set.
Signed-off-by: Carlos Maiolino <cmaiolino@redhat.com>

Changelog:
V3:
- Originally this patch removed xfs_da_state_alloc(),
per hch's suggestion, instead of removing, it has been
refactored, to also set state->{args,mp} which removes
a few lines of code.
