mm/filemap: Hoist filler_t decision to the top of do_read_cache_folio()
Now that filler_t and aops->read_folio() have the same type, we can decide
which one to use at the top of the function, and cache ->read_folio in
the filler parameter.
Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
By making filler_t the same as read_folio, we can use the same function
for both in gfs2. We can push the use of folios down one more level
in jffs2 and nfs. We also increase type safety for future users of the
various read_cache_page() family of functions by forcing the parameter
to be a pointer to struct file (or NULL).

ntfs3: Remove fsdata parameter from ntfs_extend_initialized_size()
After the last patch, Smatch reports:
fs/ntfs3/file.c:168 ntfs_extend_initialized_size()
error: uninitialized symbol 'fsdata'.
fsdata is indeed unused. This is not new, but Smatch couldn't see it
before because calls through pagecache_write_begin()/pagecache_write_end()
could theoretically call any implemention of ->write_begin/write_end,
some of which do use fsdata. Now that the calls are direct, Smatch can
see they're never used.
Fix this by simply passing NULL. While ntfs3 does pass this parameter
on to generic functions, those generic functions also never dereference
the fsdata parameter, so it's unnecessary to pass the address of a real
pointer.

floppy: use a statically allocated error counter
Interrupt handler bad_flp_intr() may cause a UAF on the recently freed
request just to increment the error count. There's no point keeping
that one in the request anyway, and since the interrupt handler uses a
static pointer to the error which cannot be kept in sync with the
pending request, better make it use a static error counter that's reset
for each new request. This reset now happens when entering
redo_fd_request() for a new request via set_next_request().
One initial concern about a single error counter was that errors on one
floppy drive could be reported on another one, but this problem is not
real given that the driver uses a single drive at a time, as that
PC-compatible controllers also have this limitation by using shared
signals. As such the error count is always for the "current" drive.
