Subject: [PATCH v5 5/9] btrfs: start transaction in btrfs_set_prop_trans
Date: Fri,  1 Mar 2019 12:34:51 +0800	[thread overview]
Message-ID: <1551414895-22925-6-git-send-email-anand.jain@oracle.com> (raw)
In-Reply-To: <1551414895-22925-1-git-send-email-anand.jain@oracle.com>

In preparation to make trans argument of btrfs_setxattr() a mandatory,
start the transaction in btrfs_set_prop_trans(). And pass the started
transaction to btrfs_set_prop() instead of NULL. This patch copies the
inode update part from btrfs_setxattr() to btrfs_set_prop_trans(),
as it is from the original code.

Signed-off-by: Anand Jain <anand.jain@oracle.com>

v5: fix c-style. Used BUG_ON, instead of ASSERT. Change log update.
v4: born
