+- Update to release 5.11
+  * Increase of the default command timeout from 20s to 30s to be
+    in-line with the kernel default settings. Similarly to the
+    kernel, the timeout for device write cache flush commands is
+    also double the default value (60s).
+  * Improved handling of timeout errors. These errors are now
+    notified using the ETIMEDOUT error code instead of the generic
+    EIO.
+  * SCSI backend driver fixes and improvements: optimized SAT
+    correctness detection for ZAC devices and faster device
+    capacity detection.
+  * Block backend driver improvements: retreive the maximum
+    number of open zones from the device sysfs attributes if the
+    kernel exposes it.
+  * Improvement of the zbc_report_zones() function that avoids
+    multiple buffer allocation/free operations for large reports.
