I was reading the LKML, then found this information regarding a
potential roadmap over at kerneltrap.org. This is the summarized bits
for 2.6 as far as order and must-haves vs. nice-to-haves vs.
not-haves-(in 2.6). FYI. XFS is listed. I just wanted t post this to
help answer/shed light on some of the more obvious questions around XFS
and 2.5 kernel tree.

I've reorganized the list into 5 categories based on the feedback
I received. Now let's see what happens :-)
In line with your expectations?
-- Guillaume
----------------------------------------------------
Likely to be merged before feature freeze:
o New VM with reverse mappings
o Add Linux Security Module (LSM)
o New MTRR (Memory Type Range Register) driver
o Add support for CPU clock/voltage scaling
o Add User-Mode Linux (UML)
o Direct pagecache BIO disk I/O
o Fix device naming issues
o Remove the 2TB block device limit
----------------------------------------------------
"The pressure is on! (TM)":
(either gets merged before feature freeze or has to wait till 2.7)
o Rewrite of the console layer
o XFS (A journaling filesystem from SGI)
o LVM (Logical Volume Manager) v2.0
o Zerocopy NFS
o Asynchronous IO (aio) support
o New kernel build system (kbuild 2.5)
o Serial driver restructure
o Replace initrd by initramfs
o ext2/ext3 large directory support: HTree index
----------------------------------------------------
Can be merged after the feature freeze and before the 2.6 release:
o Strict address space accounting
o More complete NetBEUI stack
o Add hardware sensors drivers
o PCMCIA Zoom video support
o Change all drivers to new driver model
o UDF Write support for CD-R/RW (packet writing)
o USB gadget support
----------------------------------------------------
Would be nice to have before feature freeze, but most likely 2.7:
o Improved i2o (Intelligent Input/Ouput) layer
o Read-Copy Update Mutual Exclusion
o New IO scheduler
o Per-mountpoint read-only, union-mounts, unionfs
o EVMS (Enterprise Volume Management System)
o Dynamic Probes
o Page table sharing
o ext2/ext3 online resize support
o Better event logging for enterprise systems
o UMSDOS (Unix under MS-DOS) Rewrite
o Scalable Statistics Counter
o Linux Kernel Crash Dumps
o SCTP (Stream Control Transmission Protocol)
o High resolution timers
o Overhaul PCMCIA support
o Reiserfs v4
o New lightweight library (klibc)
o New mount API
o Generic parameter/command line interface
o Full compliance with IPv6
o Serial ATA support
o Add support for NFS v4
----------------------------------------------------
Definitely 2.7:
o InfiniBand support
o Add thrashing control
o Remove all hardwired drivers from kernel
