*
* There is currently no limit on the number of irec's (extent lists)
* allowed, so heavily fragmented files may require an indirection array
* which spans multiple system pages of memory. The number of extents
* which would require this amount of contiguous memory is very large

/*
* Per-cpu incore superblock counters
*
* Simple concept, difficult implementation
*
* Basically, replace the incore superblock counters with a distributed per cpu
* counter for contended fields (e.g. free block count).
*
* Difficulties arise in that the incore sb is used for ENOSPC checking, and
* hence needs to be accurately read when we are running low on space. Hence
* there is a method to enable and disable the per-cpu counters based on how
* much "stuff" is available in them.
*
* Basically, a counter is enabled if there is enough free resource to justify
* running a per-cpu fast-path. If the per-cpu counter runs out (i.e. a local
* ENOSPC), then we disable the counters to synchronise all callers and
* re-distribute the available resources.
*
* If, once we redistributed the available resources, we still get a failure,
* we disable the per-cpu counter and go through the slow path.
*
* The slow path is the current xfs_mod_incore_sb() function. This means that
* when we disable a per-cpu counter, we need to drain it's resources back to
* the global superblock. We do this after disabling the counter to prevent
* more threads from queueing up on the counter.
*
* Essentially, this means that we still need a lock in the fast path to enable
* synchronisation between the global counters and the per-cpu counters. This
* is not a problem because the lock will be local to a CPU almost all the time
* and have little contention except when we get to ENOSPC conditions.
*
* Basically, this lock becomes a barrier that enables us to lock out the fast
* path while we do things like enabling and disabling counters and
* synchronising the counters.
*
* Locking rules:
*
* 1. XFS_SB_LOCK() before picking up per-cpu locks
* 2. per-cpu locks always picked up via for_each_online_cpu() order
* 3. accurate counter sync requires XFS_SB_LOCK + per cpu locks
* 4. modifying per-cpu counters requires holding per-cpu lock
* 5. modifying global counters requires holding XFS_SB_LOCK
* 6. enabling or disabling a counter requires holding the XFS_SB_LOCK
* and _none_ of the per-cpu locks.
*
* Disabled counters are only ever re-enabled by a balance operation
* that results in more free resources per CPU than a given threshold.
* To ensure counters don't remain disabled, they are rebalanced when
* the global resource goes above a higher threshold (i.e. some hysteresis
* is present to prevent thrashing).
*/
/*
* hot-plug CPU notifier support.
*
* We cannot use the hotcpu_register() function because it does
* not allow notifier instances. We need a notifier per filesystem
* as we need to be able to identify the filesystem to balance
* the counters out. This is acheived by having a notifier block
* embedded in the xfs_mount_t and doing pointer magic to get the
* mount pointer from the notifier block address.
