Remove the unnecessary encoding of page order into an enum and allow
->huge_fault to be called with the vma lock held instead of the mmap_lock.

It's a straight-forward conversion except that readahead_folio()
will do folio_put() in advance but it doesn't matter since folios
are still locked.
As before, since file-backed folios (pages for now) are locked, so
we could temporarily use folio->private as an internal counter to
indicate split
It can be folded into z_erofs_onlinepage_endio() to simplify the code.

{collector,collection} were once reserved in order to indicate different
runtime logical extent instance of multi-reference pclusters.
However, de-duplicated decompression has been landed in a more flexable

Make erofs_listxattr() and erofs_getxattr() routine support long xattr
name prefixes.
Although the on-disk format allows long xattr name prefixes to be placed
in the meta inode or packed inode, currently mkfs.erofs will place them
in packed inode by default. Thus let's also read long xattr name
Add erofs_read_metadata() helper reading variable-sized metadata from
inode specified by @nid. Read from meta inode if @nid is 0.

- patch 3: rename to erofs_read_metadata_bdi() and
erofs_read_metadata_nid()
v2:
- add patch 3 to introduce erofs_read_metadata() helper, so that the
long xattr name prefixes could also be read from meta inode
v1:
Since the introduction of long xattr name prefix, match_prefix() will
search among the long xattr name prefixes first and return the matched
prefix, while erofs_getxattr() expects a base prefix even when the
queried xattr name matches a long prefix.
Thus introduce match_base_prefix() helper to do
