Revision 1db175428ee374489448361213e9c3b749d14900 authored by Jan Kara on 21 October 2016, 09:33:49 UTC, committed by Dan Williams on 27 December 2016, 04:29:25 UTC
Now that dax_iomap_fault() calls ->iomap_begin() without entry lock, we can use transaction starting in ext4_iomap_begin() and thus simplify ext4_dax_fault(). It also provides us proper retries in case of ENOSPC. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

* Handling of different ABIs (personalities).
