[PATCH, needs a new owner] XFS Alloc Policies

[PATCH, needs a new owner] XFS Alloc Policies

[Mark Goodwin]

[-- Attachment #1: Type: text/plain, Size: 878 bytes --]


Series of patches, originally by Dave Chinner. This series
of 18 patches is unfinished and needs a new owner - the
feature partially implements pluggable allocation policies
for XFS.

A fairly substantial architectural write-up with community
debate/feedback on the design would be appropriate before
embarking on this. Tarball attached for the following:

01/18 xfs-fix-buf-trace
02/18 xfs-kconfig-debug
03/18 xfs-ap-inode-ag-hooks
04/18 xfs-ap-inode-agi-search-hooks
05/18 xfs-ap-data-hooks
06/18 xfs-ap-data-ac-context
07/18 xfs-ap-make-it-work
08/18 xfs-ap-per-inode-policy
09/18 xfs-ap-policy-register
10/18 xfs-ap-per-fs-policy
11/18 xfs-ap-ioctl-interface
12/18 xfs-sysfs-mount-t
13/18 xfs-ap-kobj-core
14/18 xfs-ap-handle-growfs-past-1TB
15/18 xfs-ap-cleanup-data-fallback
16/18 xfs-ap-propagate-context
17/18 xfs-ap-fix-filestreams
18/18 xfs-ap-split-inode-policy-id

Thanks for posting these.  I'm pretty sure these patches will
get some sort of makeover before beeing ready, but they are
an important building block for some of the interesting work
we're planning to do (like the multi device work or ssd-aware
allocators), so there will be some action on it.

Yep. It would be good if there was some kind of write-up on
those plans since the feature will be fairly intrusive. I assume
it's been a back-of-the-envelope-with-beer kind of discussion
so far ..
