[PATCH] VFS: pass file pointer to filesystem from ftruncate()

Browse Source 
This patch extends the iattr structure with a file pointer memeber, and adds
an ATTR_FILE validity flag for this member.

This is set if do_truncate() is invoked from ftruncate() or from
do_coredump().

The change is source and binary compatible.
