Hi Al,
After merging the vfs tree, today's linux-next build (x86_64 allmodconfig)
failed like this:
fs/orangefs/symlink.c:26:2: error: unknown field 'follow_link' specified in initializer
.follow_link = pvfs2_follow_link,
^
fs/orangefs/symlink.c:26:17: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
.follow_link = pvfs2_follow_link,
^
fs/orangefs/symlink.c:26:17: note: (near initialization for 'pvfs2_symlink_inode_operations.put_link')
Caused by commit
6b2553918d8b ("replace ->follow_link() with new method that could stay in RCU mode")
[I wish there was some way to stage these API changes :-(]
I applied the following merge fix patch (which may need more work):
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>

Subject: [PATCH] orangfs: update for follow_link to get_link change
