> The check in block_page_mkwrite meant to determine whether an offset is > within the inode size is off by one. This bug has spread to > iomap_page_mkwrite and to several filesystems (ubifs, ext4, f2fs, ceph). > To fix that, introduce a new page_mkwrite_check_truncate helper that > checks for truncate and computes the bytes in the page up to EOF, and > use that helper in the above mentioned filesystems and in btrfs. > > Signed-off-by: Andreas Gruenbacher <agrue...@redhat.com> Thank you for fixing UBIFS!
