Section 7.1.1 of the Procedure Call for the ARM Architecture (AAPCS) defines wchar_t as either an unsigned int or an unsigned short with the former preferred. Because of this requirement we need to move the definition of __wchar_t to a machine dependent header. It also cleans up the macros defining the limits of wchar_t by defining __WCHAR_MIN and __WCHAR_MAX in the same machine dependent header then using them to define WCHAR_MIN and WCHAR_MAX respectively.

| H A D | libzfs_mount.c | diff 350402 Mon Jul 29 08:25:39 MDT 2019 bapt MFC r350358: Fix a bug introduced with parallel mounting of zfs Incorporate a fix from zol: https://github.com/zfsonlinux/zfs/commit/ab5036df1ccbe1b18c1ce6160b5829e8039d94ce commit log from upstream: Fix race in parallel mount's thread dispatching algorithm Strategy of parallel mount is as follows. 1) Initial thread dispatching is to select sets of mount points that don't have dependencies on other sets, hence threads can/should run lock-less and shouldn't race with other threads for other sets. Each thread dispatched corresponds to top level directory which may or may not have datasets to be mounted on sub directories. 2) Subsequent recursive thread dispatching for each thread from 1) is to mount datasets for each set of mount points. The mount points within each set have dependencies (i.e. child directories), so child directories are processed only after parent directory completes. The problem is that the initial thread dispatching in zfs_foreach_mountpoint() can be multi-threaded when it needs to be single-threaded, and this puts threads under race condition. This race appeared as mount/unmount issues on ZoL for ZoL having different timing regarding mount(2) execution due to fork(2)/exec(2) of mount(8). `zfs unmount -a` which expects proper mount order can't unmount if the mounts were reordered by the race condition. There are currently two known patterns of input list `handles` in `zfs_foreach_mountpoint(..,handles,..)` which cause the race condition. 1) #8833 case where input is `/a /a /a/b` after sorting. The problem is that libzfs_path_contains() can't correctly handle an input list with two same top level directories. There is a race between two POSIX threads A and B, * ThreadA for "/a" for test1 and "/a/b" * ThreadB for "/a" for test0/a and in case of #8833, ThreadA won the race. Two threads were created because "/a" wasn't considered as `"/a" contains "/a"`. 2) #8450 case where input is `/ /var/data /var/data/test` after sorting. The problem is that libzfs_path_contains() can't correctly handle an input list containing "/". There is a race between two POSIX threads A and B, * ThreadA for "/" and "/var/data/test" * ThreadB for "/var/data" and in case of #8450, ThreadA won the race. Two threads were created because "/var/data" wasn't considered as `"/" contains "/var/data"`. In other words, if there is (at least one) "/" in the input list, the initial thread dispatching must be single-threaded since every directory is a child of "/", meaning they all directly or indirectly depend on "/". In both cases, the first non_descendant_idx() call fails to correctly determine "path1-contains-path2", and as a result the initial thread dispatching creates another thread when it needs to be single-threaded. Fix a conditional in libzfs_path_contains() to consider above two.
