Subject: [PATCH] Linux-5.19: Remove flags from aops->write_begin
The Linux 5.19 commits:
fs: Remove aop flags parameter from grab_cache_page_write_begin()
(b7446e7c)
fs: Remove flags parameter from aops->write_begin (9d6b0cd7)
removed the flags parameter from the address space operations
'write_begin' as well as removing the flags parameter from the Linux
function 'grab_cache_page_write_begin'.
Add an autoconf test to see if grab_cache_page_write_begin takes 2 or
3 parameters. Use this as a test to determine if the address space
operations 'write_begin' takes a flags parameter.
Create a version of afs_linux_write_begin that does not take a flags
parameter, which also calls grab_cache_page_write_begin without flags.

Subject: [PATCH] Linux-5.19: Rename aops readpage to read_folio
With Linux commits:
mm,fs: Remove aops->readpage (7e0a126519)
fs: Introduce aops->read_folio (5efe7448a1)
the address space operations method 'readpage' was replaced with
read_folio. The operation behaves the same, except instead of taking a
struct page parameter, the new function takes a folio structure.
Add an autoconf test for the address space operation entry read_folio
Replace the references to an address space operations' readpage with
read_folio. Note that the function Linux page_folio can be used to
obtain the required pointer to the folio for a given page.
Introduce afs_linux_read_folio that accepts a folio and calls
afs_linux_readpage with the page associated with that folio.

Subject: [PATCH] Linux: Introduce file mapping readpage helpers
Create a helper function that determines if a file's
i_mapping->a_ops->readpage
is NULL.
Create a helper function that calls a file's
i_mapping->a_ops->readpage
There are no functional changes with this commit.
Note: This commit isolates references to 'readpage' so that future
commits can change the name in a more straight forward manner.
