Based on the original XIP documentation, this documents the current

To help people transition, accept the 'xip' mount option (and report it
in /proc/mounts), but print a message encouraging people to switch over

Jan Kara pointed out that calling ext2_xip_verify_sb() in ext2_remount()
doesn't make sense, since changing the XIP option on remount isn't
allowed. It also doesn't make sense to re-check whether blocksize is
supported since it can't change between mounts.
Replace the call to ext2_xip_verify_sb()

When DAX is enabled, it uses i_mmap_mutex as a protection against
truncate during page fault. This inevitably forces i_mmap_mutex to rank
outside of a transaction start and thus we have to avoid calling
pagecache purging operations when transaction is started.

In order to support accesses to larger chunks of memory, pass in a
'size' parameter (counted in bytes), and return the amount available at
that address.
Add a new helper function, bdev_direct_access(), to handle common
functionality including partition handling, checking for the sector
being page-
Pagecache faults recheck i_size after taking the page lock to ensure that
the fault didn't race against a truncate. We don't have a page to lock
in the XIP case, so use the i_mmap_mutex instead. It is locked in the
truncate path in unmap_mapping_range() after updating i_size. So while

For DAX, we want to be able to copy between iovecs and kernel addresses
that don't necessarily have a struct page. This is a fairly simple
rearrangement for bvec iters to kmap the pages outside and pass them in,
but for user iovecs it gets more complicated because we might t

Instead of calling aops->get_xip_mem from the fault handler, the
filesystem passes a get_block_t that is used to find the appropriate
blocks.

This new function allows us to support hole-punch for XIP files by zeroing
a partial page, as opposed to the xip_truncate_page() function which can
only truncate to the end of the page. Reimplement xip_truncate_page() as
a macro that calls xip_zero_page_range().

Use the generic AIO infrastructure instead of custom read and write
methods. In addition to giving us support for AIO, this adds the missing

This is practically generic code; other filesystems will want to call
it from other places, but there's nothing ext2-specific about it.
Make it a little more generic by allowing it to take a count of the number
of bytes to zero rather than fixing it to a single page. Thanks to Dave

One of the primary uses for NV-DIMMs is to expose them as a block device
and use a filesystem to store files on the NV-DIMM. While that works,
it currently wastes memory and CPU time buffering the files in the page
cache. We have support in ext2 for bypassing the page cache
