Linux 6.6 compat: fsync_bdev() has been removed in favor of sync_blockdev()

Browse Source 
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.
