Subject: Use filemap_fdata{sync,wait} directly (available in 2.4.5 and above)
X-Git-Tag: openafs-devel-1_3_0~24
X-Git-Url: https://git.openafs.org/?p=openafs.git;a=commitdiff_plain;h=30c69dae289b0184d2d38e4d9781de5a2c81952c

Use filemap_fdata{sync,wait} directly (available in 2.4.5 and above)
rather than write_inode_now(), which steals afs inodes and puts them
on the global inode lists.
