The patch titled
Turn do_sync_file_range() into do_sync_mapping_range()
has been removed from the -mm tree. Its filename was
turn-do_sync_file_range-into-do_sync_mapping_range.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Turn do_sync_file_range() into do_sync_mapping_range()
From: Mark Fasheh <[EMAIL PROTECTED]>
do_sync_file_range() accepts a file * from which it takes an address_space to
sync. Abstract out the bulk of the function into do_sync_mapping_range()
which takes the address_space directly. This way callers who want to sync an
address_space directly can take advantage of the functionality provided.
do_sync_file_range() is preserved as a small wrapper around
do_sync_mapping_range().
Ocfs2 in particular would like to use this to initiate a sync of a specific
inode range during truncate, where a file * may not be available.
