Daniel Micay	e94fe50a0d	include zero byte size class in stats ... The allocations don't consume any actual memory, but it does still use up the virtual memory assigned to the size class and requires metadata.	2019-04-06 22:43:56 -04:00
Daniel Micay	712748aaa8	add implementation of Android mallinfo extensions ... These are used internally by Bionic to implement malloc_info.	2019-04-06 22:39:01 -04:00
Daniel Micay	0f107cd2a3	only provide malloc_info stub for glibc ... This has a proper implementation in Bionic outside of the malloc implementation via the extended mallinfo API.	2019-04-06 22:01:12 -04:00
Daniel Micay	350d0e5fd2	add real mallinfo implementation for Android ... Android Q uses the mallinfo implementation in the ART GC: c220f98180 1575267302	2019-04-06 20:54:26 -04:00

Daniel Micay	4a000d96e2	pkey state is now preserved on fork for Linux 5.0+ ... This patch is going to be backported to stable kernels, so the check could be expanded to allow recent enough stable kernel branches.	2019-03-20 11:05:31 -04:00
