Subject: [PATCH 2/5] btrfs: kill __btrfs_set_prop()
Date: Fri,  8 Feb 2019 15:02:32 +0800
Message-ID: <1549609355-11053-3-git-send-email-anand.jain@oracle.com> (raw)
In-Reply-To: <1549609355-11053-1-git-send-email-anand.jain@oracle.com>

btrfs_set_prop() is a redirect to __btrfs_set_prop() with the
transaction handler equal to NULL. And __btrfs_set_prop() inturn diectly
uses trans to do_setxattr() which when trans is NULL creates a transaction.

Instead rename __btrfs_set_prop() to btrfs_set_prop(), and update the
caller with NULL argument.
