CVE-2024-26869

In the Linux kernel, the following vulnerability has been resolved:

f2fs: fix to truncate meta inode pages forcely

Below race case can cause data corruption:

Thread A				GC thread
					- gc_data_segment
					 - ra_data_block
					  - locked meta_inode page
- f2fs_inplace_write_data
 - invalidate_mapping_pages
 : fail to invalidate meta_inode page
   due to lock failure or dirty|writeback
   status
 - f2fs_submit_page_bio
 : write last dirty data to old blkaddr
					 - move_data_block
					  - load old data from meta_inode page
					  - f2fs_submit_page_write
					  : write old data to new blkaddr

Because invalidate_mapping_pages() will skip invalidating page which
has unclear status including locked, dirty, writeback and so on, so
we need to use truncate_inode_pages_range() instead of
invalidate_mapping_pages() to make sure meta_inode page will be dropped.
