c2ec175c39 mm: page_mkwrite change prototype to match fault
Change the page_mkwrite prototype to take a struct vm_fault, and return
VM_FAULT_xxx flags.  There should be no functional change.

This makes it possible to return much more detailed error information to
the VM (and also can provide more information eg.  virtual_address to the
driver, which might be important in some special cases).

This is required for a subsequent fix.  And will also make it easier to
merge page_mkwrite() with fault() in future.

27174203f5 xfs: cleanup uuid handling
The uuid table handling should not be part of a semi-generic uuid library
but in the XFS code using it, so move those bits to xfs_mount.c and
refactor the whole glob to make it a proper abstraction.

1a5902c5d2 xfs: remove m_attroffset
With the upcoming v3 inodes the default attroffset needs to be calculated
for each specific inode, so we can't cache it in the superblock anymore.

Also replace the assert for wrong inode sizes with a proper error check
also included in non-debug builds.  Note that the ENOSYS return for
that might seem odd, but that error is returned by xfs_mount_validate_sb
for all theoretically valid but not supported filesystem geometries.

bddaafa11a xfs: pagecache usage optimization
Hi.

I introduced "is_partially_uptodate" aops for XFS.

A page can have multiple buffers and even if a page is not uptodate,
some buffers can be uptodate on pagesize != blocksize environment.

This aops checks that all buffers which correspond to a part of a file
that we want to read are uptodate. If so, we do not have to issue actual
read IO to HDD even if a page is not uptodate because the portion we
want to read are uptodate.

"block_is_partially_uptodate" function is already used by ext2/3/4.
With the following patch random read/write mixed workloads or random read
after random write workloads can be optimized and we can get performance
improvement.

I did a performance test using the sysbench.

#sysbench --num-threads=4 --max-requests=100000 --test=fileio --file-num=1 \
--file-block-size=8K --file-total-size=1G --file-test-mode=rndrw \
