           inode having been discarded already.  Whether this can actually ever
           happen is unclear however so it is worth waiting until someone hits
           the problem.
-        - Enable the code for setting the NT4 compatibility flag when we start
-          making NTFS 1.2 specific modifications.
+
+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
+          fs/ntfs/unistr.c::ntfs_nlstoucs() in fs/ntfs/namei.c::ntfs_lookup().
+        - Semaphore to mutex conversion.  (Ingo Molnar)
 
 2.1.26 - Minor bug fixes and updates.

 /*
+ * The following xfs_ext_irec_t struct introduces a second (top) level
+ * to the in-core extent allocation scheme. These structs are allocated
+ * in a contiguous block, creating an indirection array where each entry
+ * (irec) contains a pointer to a buffer of in-core extent records which
+ * it manages. Each extent buffer is 4k in size, since 4k is the system
+ * page size on Linux i386 and systems with larger page sizes don't seem
+ * to gain much, if anything, by using their native page size as the
+ * extent buffer size. Also, using 4k extent buffers everywhere provides
+ * a consistent interface for CXFS across different platforms.
+ *
+ * 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
+ * and should not cause problems in the foreseeable future. However,
+ * if the memory needed for the contiguous array ever becomes a problem,
+ * it is possible that a third level of indirection may be required.

+/*
+ * 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.
