Subject: mm: use vma_start_write_killable() in mm syscalls
Date: Thu, 26 Mar 2026 01:08:32 -0700
Replace vma_start_write() with vma_start_write_killable() in syscalls,
improving reaction time to the kill signal.
In a number of places we now lock VMA earlier than before to avoid doing
work and undoing it later if a fatal signal is pending. This is safe
because the moves are happening within sections where we already hold the
mmap_write_lock, so the moves do not change the locking order relative to
other kernel locks.
