Hi all,

Today's linux-next merge of the xfs tree got a conflict in:

  fs/f2fs/file.c

between commit:

  360985573b55 ("f2fs: separate f2fs i_flags from fs_flags and ext4 i_flags")

from the f2fs tree and commits:

  de2baa49bbae ("vfs: create a generic checking and prep function for FS_IOC_SETFLAGS")
  3dd3ba36a8ee ("vfs: create a generic checking function for FS_IOC_FSSETXATTR")

from the xfs tree.

I fixed it up (I think - see below) and can carry the fix as necessary.
This is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Hi Stephen,

Could you add my iomap-for-next and vfs-for-next branches to linux-next,
please?  They can be found here:

git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git#iomap-for-next
git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git#vfs-for-next

I've decided that trying to munge all that through the xfs for-next
branch is too much insanity and splitting them up will help me prevent
my head from falling off.

Just out of interest, do you intend to send these directly to Linus, or
via another tree?

Added from today.

Thanks for adding your subsystem tree as a participant of linux-next.  As
you may know, this is not a judgement of your code.  The purpose of
linux-next is for integration testing and to lower the impact of
conflicts between subsystems in the next merge window. 

You will need to ensure that the patches/commits in your tree/series have
been:
     * submitted under GPL v2 (or later) and include the Contributor's
        Signed-off-by,
     * posted to the relevant mailing list,
     * reviewed by you (or another maintainer of your subsystem tree),
     * successfully unit tested, and 
     * destined for the current or next Linux merge window.

Basically, this should be just what you would send to Linus (or ask him
to fetch).  It is allowed to be rebased if you deem it necessary.

The iomap stuff I'd definitely send directly to Linus.

For vfs stuff, it depends.  For work in the core vfs I'll probably just
keep sending patches through Al, but for treewide things like ioctl
cleanups I suspect it'll be easier to let them soak in -next and then
send them directly.

I also dropped the f2fs parts of the setflags/fssetxattr patches because
while I think your fix from yesterday's for-next is correct, I prefer to
let Eric Biggers' cleanup land through the f2fs tree before I try to
clean up f2fs again.  There shouldn't be any harm in letting that lag a
little while longer.

I don't think this is the correct resolution.  Now f2fs_setflags_common() is
meant to take the f2fs on-disk i_flags, which aren't necessarily the same as the
flags passed to the FS_IOC_SETFLAGS ioctl.  So it's not appropriate to call
vfs_ioc_setflags_prepare() in it.  It should be in f2fs_ioc_setflags() instead.

I've pushed up what I think is the correct resolution to
https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git/log/?h=f2fs-setflags-resolved

Here is my diff of fs/f2fs/file.c from f2fs/dev.  Darrick, can you check that
this is what you would have done if you had patched f2fs/dev instead of v5.2?

Yep, that's roughly what I was planning to do to connect f2fs to the
checking functions.

I withdrew the fs/f2fs/ parts of the setflags/fssetxattr cleanups from
the branch with the intent to fix it after f2fs-dev lands, because I
think this is too messy a merge resolution to push through Linus.

Would you mind resending this with a proper subject line and SOB? :)
