xfs: Delay Ready Attributes
Hi all,
This set is a subset of a larger series for Dealyed Attributes. Which is a
subset of a yet larger series for parent pointers. Delayed attributes allow
attribute operations (set and remove) to be logged and committed in the same
way that other delayed operations do. This allows more complex operations (like
parent pointers) to be broken up into multiple smaller transactions. To do
this, the existing attr operations must be modified to operate as a delayed
operation. This means that they cannot roll, commit, or finish transactions.
Instead, they return -EAGAIN to allow the calling function to handle the
transaction. In this series, we focus on only the delayed attribute portion.
We will introduce parent pointers in a later set.
The set as a whole is a bit much to digest at once, so I usually send out the
smaller sub series to reduce reviewer burn out. But the entire extended series
is visible through the included github links.
Updates since v19: Added Darricks fix for the remote block accounting as well as
some minor nits about the default assert in xfs_attr_set_iter. Spent quite
a bit of time testing this cycle to weed out any more unexpected bugs. No new
test failures were observed with the addition of this set.
xfs: Fix default ASSERT in xfs_attr_set_iter
Replaced the assert with ASSERT(0);
xfs: Add delay ready attr remove routines
Added Darricks fix for remote block accounting
This series can be viewed on github here:
https://github.com/allisonhenderson/xfs_work/tree/delay_ready_attrs_v20
As well as the extended delayed attribute and parent pointer series:
https://github.com/allisonhenderson/xfs_work/tree/delay_ready_attrs_v20_extended
And the test cases:
https://github.com/allisonhenderson/xfs_work/tree/pptr_xfstestsv3
In order to run the test cases, you will need have the corresponding xfsprogs
changes as well. Which can be found here:
https://github.com/allisonhenderson/xfs_work/tree/delay_ready_attrs_xfsprogs_v20
https://github.com/allisonhenderson/xfs_work/tree/delay_ready_attrs_xfsprogs_v20_extended
To run the xfs attributes tests run:
check -g attr
To run as delayed attributes run:
export MOUNT_OPTIONS="-o delattr"
check -g attr
To run parent pointer tests:
check -g parent
I've also made the corresponding updates to the user space side as well, and ported anything
they need to seat correctly.
Questions, comment and feedback appreciated!
Thanks all!
Allison

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
