Robert Love 97f93ad8e2 ashmem for 2.6.27. ... Forward port of ashmem to 2.6.27. Signed-off-by: Robert Love <rlove@google.com> ashmem: Don't install fault handler for private mmaps. Ashmem is used to create named private heaps. If this heap is backed by a tmpfs file it will allocate two pages for every page touched. In 2.6.27, the extra page would later be freed, but 2.6.29 does not scan anonymous pages when running without swap so the memory is not freed while the file is referenced. This change changes the behavior of private ashmem mmaps to match /dev/zero instead tmpfs. Signed-off-by: Arve Hjønnevåg <arve@android.com> ashmem: Add common prefix to name reported in /proc/pid/maps Signed-off-by: Arve Hjønnevåg <arve@android.com> ashmem: don't require a page aligned size This makes ashmem more similar to shmem and mmap, by not requiring the specified size to be page aligned, instead rounding it internally as needed.
