-From 664d487a5dbd758216ac613934a4080fcc1de347 Mon Sep 17 00:00:00 2001
-From: Brian Behlendorf <behlendorf1@llnl.gov>

-Subject: [PATCH] Fix lseek(SEEK_DATA/SEEK_HOLE) mmap consistency
-
-When using lseek(2) to report data/holes memory mapped regions of
-the file were ignored.  This could result in incorrect results.
-To handle this zfs_holey_common() was updated to asynchronously
-writeback any dirty mmap(2) regions prior to reporting holes.
-
-Additionally, while not strictly required, the dn_struct_rwlock is
-now held over the dirty check to prevent the dnode structure from
-changing.  This ensures that a clean dnode can't be dirtied before
-the data/hole is located.  The range lock is now also taken to
-ensure the call cannot race with zfs_write().
-
-Furthermore, the code was refactored to provide a dnode_is_dirty()
-helper function which checks the dnode for any dirty records to
-determine its dirtiness.

-Subject: [PATCH] Restore dirty dnode detection logic
-
-In addition to flushing memory mapped regions when checking holes,
-commit de198f2d95 modified the dirty dnode detection logic to check
-the dn->dn_dirty_records instead of the dn->dn_dirty_link.  Relying
-on the dirty record has not be reliable, switch back to the previous
-method.
