Hello,

the patch series below addresses some issues with test ext4/001. First two
patches improve _link_out_file helper function to allow selection of output
(or in general linking any file when using _link_out_file_named() variant)
based on a feature string (usually mount options, fs features, operating
system) passed to the function (if no feature string is passed, the function
defaults to using "operating system name","mount options"). This feature
is useful when e.g. different mount options change behavior of the filesystem
and thus different output is generated but we want to have the test working
for all mount options.

Patch 3 uses the output selection function in ext4/001 to select different
output files based on mount options.

Comments welcome!

Changes since v1:
* rebased on the current head of xfstests
* integrated output selection with _link_out_file and converted all tests
  using it

From: Jan Kara <jack@suse.com>

Currently _link_output_file() selects output file suffix based on the
current operating system. Make it more versatile by allowing selection
of output file suffix based on any feature string. The idea is that
in config file ($seq.cfg) there are several lines like:

feat1,feat2: suffix

The function is passed a feature string (or uses os_name,MOUNT_OPTIONS
if no argument is passed) and selects output file with a suffix for
which all features are present in the feature string. If there is no
matching line, output with 'default' suffix is selected.

Update all tests using _link_out_file to the new calling convention.

I made a slight change so that if $seqfull.cfg doesn't exist, we use
./common/default.cfg instead.  This avoids the need to create a large
number of identical files:

What do you think?

commit 37c2d44b6cc6772f0daa10761fb532b5662dc6fc
Author: Jan Kara <jack@suse.com>
Date:   Tue Nov 24 11:39:57 2015 +0100

    common: Improve _link_output_file to be more versatile
    
    Currently _link_output_file() selects output file suffix based on the
    current operating system. Make it more versatile by allowing selection
    of output file suffix based on any feature string. The idea is that
    in config file ($seq.cfg) there are several lines like:
    
    feat1,feat2: suffix
    
    The function is passed a feature string (or uses os_name,MOUNT_OPTIONS
    if no argument is passed) and selects output file with a suffix for
    which all features are present in the feature string. If there is no
    matching line, output with 'default' suffix is selected.
    
    Update all tests using _link_out_file to the new calling convention.

So I'm somewhat undecided whether this is better or not ;). It certainly
saves us some churn with identical .cfg files for linux vs irix configs
but OTOH I don't expect there to be much more .cfg files selecting between
irix and linux so this is mostly one-time issue. So I guess I'll leave it
upto Dave and his taste to decide what he finds better.

Maybe it's time to drop IRIX support?  I'm pretty sure it hasn't worked
for a long time..

I'll take the one-time change here, but as Christoph suggested it
really is getting to the point where we should stop considering
xfstests to be a cross-platform test suite. Just another cleanup to
be done...

From: Jan Kara <jack@suse.com>

Depending on mount options, we handle unwritten extents somewhat
differently. So sometimes we end up zeroing out unwritten extent and
converting it to written one and sometimes we just split it. Choose
expected output based on mount options.
