Subject: Documentation on Replacement of Deprecated O_SYNC_* FS flags/calls

Hi,

I'm trying to port e2compr patches to 2.6.35.2, and I've run into the
following issue. The code here, that I need to patch into fs/ext2/file.c:

=============
if (status >= 0) {
if ((file->f_flags & O_SYNC) || IS_SYNC(inode)) {
if (ei->i_compr_flags & EXT2_OSYNC_INODE) {
osync_already = 1;
} else {
osync_already = 0;
ei->i_compr_flags |= EXT2_OSYNC_INODE;
}

/* Should 2nd arg be inode->i_mapping? */
status = generic_osync_inode(inode, file->f_mapping,
OSYNC_METADATA|OSYNC_DATA);
if (osync_already == 0) {
ei->i_compr_flags &= ~EXT2_OSYNC_INODE;
}
}
}
=============

uses the deprecated O_SYNC_* flags that have been deprecated and removed
around the 2.6.31 era. Is there any documentation available on the new
way this should be done?

Many thanks.

Gordan
