+
+2.1.27 - Various bug fixes and cleanups.
+
+ - Fix two compiler warnings on Alpha. Thanks to Andrew Morton for
+ reporting them.
+ - Fix an (innocent) off-by-one error in the runlist code.
+ - Fix a buggette in an "should be impossible" case handling where we
+ continued the attribute lookup loop instead of aborting it.
+ - Use buffer_migrate_page() for the ->migratepage function of all ntfs
+ address space operations.
+ - Fix comparison of $MFT and $MFTMirr to not bail out when there are
+ unused, invalid mft records which are the same in both $MFT and
+ $MFTMirr.
+ - Add support for sparse files which have a compression unit of 0.
+ - Remove all the make_bad_inode() calls. This should only be called
+ from read inode and new inode code paths.
+ - Limit name length in fs/ntfs/unistr.c::ntfs_nlstoucs() to maximum
+ allowed by NTFS, i.e. 255 Unicode characters, not including the
+ terminating NULL (which is not stored on disk).
+ - Improve comments on file attribute flags in fs/ntfs/layout.h.
+ - Fix a bug in fs/ntfs/inode.c::ntfs_read_locked_index_inode() where we
+ forgot to update a temporary variable so loading index inodes which
+ have an index allocation attribute failed.
+ - Add a missing call to flush_dcache_mft_record_page() in
+ fs/ntfs/inode.c::ntfs_write_inode().
+ - Handle the recently introduced -ENAMETOOLONG return value from

+ * 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).
