[Openmp-commits] [PATCH] D141227: [OpenMP][libomptarget] Implement memory lock/unlock API in NextGen plugins

[Kevin Sala Penadés via Phabricator via Openmp-commits]

Rebasing and adding support for ref counting on locked buffers and allow certain overlapping. Given an already locked buffer A, other buffers that are fully contained inside A can be locked, even if they are smaller than A. Extending an existing locked buffer is not allowed. The original region is unlocked once all its users have released the locked buffer and sub-buffers.
