dnl # torvalds/linux@7994e6f7254354e03028a11f98a27bd67dace9f1 reworked
dnl # where inode_sync_wait() is called.
dnl #
dnl # Prior to these changes it would occur in end_writeback() but due
dnl # to various issues (described in the above commits) it has been
dnl # moved to evict(). This changes the ordering is which sync occurs
dnl # but otherwise doesn't impact the zpl implementation.
dnl #
dnl # The major impact here is the renaming of end_writeback() to
dnl # clear_inode(). However, care must be taken when detecting this
dnl # API change because as recently as 2.6.35 there was a clear_inode()
dnl # function. However, it was made obsolete by the evict_inode() API
dnl # change at the same time.
dnl #
dnl # Therefore, to ensure we have the correct API we only allow the
dnl # clear_inode() compatibility code to be defined iff the evict_inode()
dnl # functionality is also detected.
