 * The 'AT_NO_ATTR_SYNC' macro is deprecated, please use the standard 'AT_STATX_DONT_SYNC'
   macro. The 'AT_NO_ATTR_SYNC' macro will be removed in the future.
+* Trimming of PGLog dups is now controlled by the size instead of the version.
+  This fixes the PGLog inflation issue that was happening when the on-line
+  (in OSD) trimming got jammed after a PG split operation. Also, a new off-line
+  mechanism has been added: `ceph-objectstore-tool` got `trim-pg-log-dups` op
+  that targets situations where OSD is unable to boot due to those inflated dups.
+  If that is the case, in OSD logs the "You can be hit by THE DUPS BUG" warning
+  will be visible.
