@ any_inode_change
historical behavior, resave an inode on any metadata change
@ mtime_size
default behavior since release 2.6.0 resave only if file size of mtime changed
@ inode_type
only consider the file type
@ ignore_owner
consider any available field except ownership fields
@ mtime
consider any available field except ownership and permission fields
@ all
consider any available field for comparing inodes
@ argon2
argon2 hash algo
@ md5
MD5 algorithm.
@ none
no hashing algorithm
@ sha1
SHA1 algorithm.
@ sha512
SHA-512 algorithm.
are defined here basic integer types that tend to be portable
include macro defined by the configure script and some specific additional ones
