+From 9161ace4a02ea37b45f7ae613ea1d095a65d588d Mon Sep 17 00:00:00 2001
+From: Brian Behlendorf <behlendorf1@llnl.gov>
+Date: Fri, 15 Jun 2018 15:05:21 -0700
+Subject: [PATCH] Linux compat 4.18: check_disk_size_change()
+
+Added support for the bops->check_events() interface which was
+added in the 2.6.38 kernel to replace bops->media_changed().
+Fully implementing this functionality allows the volume resize
+code to rely on revalidate_disk(), which is the preferred
+mechanism, and removes the need to use check_disk_size_change().
+
+In order for bops->check_events() to lookup the zvol_state_t
+stored in the disk->private_data the zvol_state_lock needs to
+be held. Since the check events interface may poll the mutex
+has been converted to a rwlock for better concurrently. The
+rwlock need only be taken as a writer in the zvol_free() path
+when disk->private_data is set to NULL.
+
+The configure checks for the block_device_operations structure
+were consolidated in a single kernel-block-device-operations.m4
+file.
+
+The ZFS_AC_KERNEL_BDEV_BLOCK_DEVICE_OPERATIONS configure checks
+and assoicated dead code was removed. This interface was added
+to the 2.6.28 kernel which predates the oldest supported 2.6.32
+kernel and will therefore always be available.
+
+Updated maximum Linux version in META file. The 4.17 kernel
+was released on 2018-06-03 and ZoL is compatible with the
+finalized kernel.

+From: Brian Behlendorf <behlendorf1@llnl.gov>
+Date: Sun, 12 Aug 2018 18:22:03 -0400
+Subject: [PATCH] Linux 4.18 compat: inode timespec -> timespec64
+
+Commit torvalds/linux@95582b0 changes the inode i_atime, i_mtime,
+and i_ctime members form timespec's to timespec64's to make them
+2038 safe. As part of this change the current_time() function was
+also updated to return the timespec64 type.
+
+Resolve this issue by introducing a new inode_timespec_t type which
+is defined to match the timespec type used by the inode. It should
+be used when working with inode timestamps to ensure matching types.
+
+The timestruc_t type under Illumos was used in a similar fashion but
+was specified to always be a timespec_t. Rather than incorrectly
+define this type all timespec_t types have been replaced by the new
+inode_timespec_t type.
+
+Finally, the kernel and user space 'sys/time.h' headers were aligned
+with each other. They define as appropriate for the context several
+constants as macros and include static inline implementation of
+gethrestime(), gethrestime_sec(), and gethrtime().
