2020-08-04Use 1 fragmentation component per IP stackGhanan Gowripalan
This will help manage memory consumption by IP reassembly when receiving IP fragments on multiple network endpoints. Previously, each endpoint would cap memory consumption at 4MB, but with this change, each IP stack will cap memory consumption at 4MB. No behaviour changes. PiperOrigin-RevId: 324913904

2020-08-04Add reference counting utility to VFS2.Dean Deng
The utility has several differences from the VFS1 equivalent: - There are no weak references, which have a significant overhead - In order to print useful debug messages with the type of the reference- counted object, we use a generic Refs object with the owner type as a template parameter. In vfs1, this was accomplished by storing a type name and caller stack directly in the ref count (as in vfs1), which increases the struct size by 6x. (Note that the caller stack was needed because fs types like Dirent were shared by all fs implementations; in vfs2, each impl has its own data structures, so this is no longer necessary.) As an example, the utility is added to tmpfs.inode. Updates #1486. PiperOrigin-RevId: 324906582

The variable name is g which is collision with the reserved name for R28. This leads to bazel build failure on ARM with following information: (register+register) not supported on this architecture rename it from g to ptr (referenced from golang source code) Signed-off-by: Howard Zhang <howard.zhang@arm.com>
