Roadmap:
-2.6.35 Inclusion in mainline as an experimental mount option
- => approximately 2-3 months to merge window
- => needs to be in xfs-dev tree in 4-6 weeks
- => code is nearing readiness for review
-
2.6.37 Remove experimental tag from mount option
=> should be roughly 6 months after initial merge
=> enough time to:
trace_xfs_writepage(inode, page, 0);

+ * Refuse to write the page out if we are called from reclaim context.
+ *
+ * This is primarily to avoid stack overflows when called from deep
+ * used stacks in random callers for direct reclaim, but disabling
+ * reclaim for kswap is a nice side-effect as kswapd causes rather
+ * suboptimal I/O patters, too.
+ *
+ * This should really be done by the core VM, but until that happens
+ * filesystems like XFS, btrfs and ext4 have to take care of this
