+Subject: [PATCH] Linux 6.6 compat: use inode_get/set_ctime*(...)
+
+In Linux commit 13bc24457850583a2e7203ded05b7209ab4bc5ef, direct access
+to the i_ctime member of struct inode was removed. The new approach is
+to use accessor methods that exclusively handle passing the timestamp
+around by value. This change adds new tests for each of these functions
+and introduces zpl_* equivalents in include/os/linux/zfs/sys/zpl.h. In
+where the inode_get/set_ctime*() functions exist, these zpl_* calls will
+be mapped to the new functions. On older kernels, these macros just wrap
+direct-access calls. The code that operated on an address of ip->i_ctime
+to call ZFS_TIME_DECODE() now will take a local copy using
+zpl_inode_get_ctime(), and then pass the address of the local copy when
+performing the ZFS_TIME_DECODE() call, in all cases, rather than
+directly accessing the member.

+Subject: [PATCH] Linux 6.6 compat: generic_fillattr has a new u32 request_mask
+ added at arg2
+
+In commit 0d72b92883c651a11059d93335f33d65c6eb653b, a new u32 argument
+for the request_mask was added to generic_fillattr. This is the same
+request_mask for statx that's present in the most recent API implemented
+by zpl_getattr_impl. This commit conditionally adds it to the
+zpl_generic_fillattr(...) macro, as well as the zfs_getattr_fast(...)
+implementation, when configure determines it's present in the kernel's
+generic_fillattr(...).

+Subject: [PATCH] Linux 6.6 compat: fsync_bdev() has been removed in favor of
+ sync_blockdev()
+
+In Linux commit 560e20e4bf6484a0c12f9f3c7a1aa55056948e1e, the
+fsync_bdev() function was removed in favor of sync_blockdev() to do
+(roughly) the same thing, given the same input. This change
+conditionally attempts to call sync_blockdev() if fsync_bdev() isn't
+discovered during configure.

+
+With Linux v6.6.0 and GCC 12, when debug build is configured,
+implicit conversion error is raised while converting
+'enum <anonymous>' to 'boolean_t'. Use 'B_TRUE' instead of
+'true' to fix the issue.
