Subject: [PATCH v2 15/21] btrfs: drop unnecessary arguments from clustered allocation functions
Date: Wed, 12 Feb 2020 16:20:42 +0900 [thread overview]
Message-ID: <20200212072048.629856-16-naohiro.aota@wdc.com> (raw)
In-Reply-To: <20200212072048.629856-1-naohiro.aota@wdc.com>
Now that, find_free_extent_clustered() and find_free_extent_unclustered()
can access "last_ptr" from the "clustered" variable. So, we can drop it
from the arguments.
