[PATCH v3 0/2] man/man2/mremap.2: describe multiple mapping move, shrink

Posted by Lorenzo Stoakes 2 months, 1 week ago

We have added new functionality to mremap() in Linux 6.17, permitting the
move of multiple VMAs when performing a move alone (that is - providing
MREMAP_MAYMOVE | MREMAP_FIXED flags and specifying old_size == new_size).

We document this new feature.

Additionally, we document previously undocumented behaviour around
shrinking of input VMA ranges which permits the input range to span
multiple VMAs.

v3:
* Use more precise language around mremap() move description as per Jann.
* Fix some typos in commit messages.

v2:
* Split out the two man page changes as requested by Alejandro.
