Closes#11963Closes#11965
While OpenZFS does permit breaking changes to the libzfs API, we should
avoid these changes when reasonably possible, and take steps to mitigate
the impact to consumers when changes are necessary.
Commit e4288a8397 made a libzfs API change that is especially
difficult for consumers because there is no change to the function
signatures, only to their behavior. Therefore, consumers can't notice
that there was a change at compile time. Also, the API change was
incompletely and incorrectly documented.
The commit message mentions `zfs_get_prop()` [sic], but all callers of
`get_numeric_property()` are impacted: `zfs_prop_get()`,
`zfs_prop_get_numeric()`, and `zfs_prop_get_int()`.
`zfs_prop_get_int()` always calls `get_numeric_property(src=NULL)`, so
it assumes that the filesystem is not mounted. This means that e.g.
`zfs_prop_get_int(ZFS_PROP_MOUNTED)` always returns 0.
The documentation says that to preserve the previous behavior, callers
should initialize `*src=ZPROP_SRC_NONE`, and some callers were changed
to do that. However, the existing behavior is actually preserved by
initializing `*src=ZPROP_SRC_ALL`, not `NONE`.
The code comment above `zfs_prop_get()` says, "src: ... NULL will be
treated as ZPROP_SRC_ALL.". However, the code actually treats NULL as
ZPROP_SRC_NONE. i.e. `zfs_prop_get(src=NULL)` assumes that the
filesystem is not mounted.
There are several existing calls which use `src=NULL` which are impacted
by the API change, most noticeably those used by `zfs list`, which now
assumes that filesystems are not mounted. For example,
`zfs list -o name,mounted` previously indicated whether a filesystem was
mounted or not, but now it always (incorrectly) indicates that the
filesystem is not mounted (`MOUNTED: no`). Similarly, properties that
are set at mount time are ignored. E.g. `zfs list -o name,atime` may
display an incorrect value if it was set at mount time.
To address these problems, this commit reverts commit e4288a8397:
"zfs get: don't lookup mount options when using "-s local""

Looking up mount options can be very expensive on servers with many
mounted file systems. When doing "zfs get" with any "-s" option that
does not include "temporary", the mount list will never be used. This
commit optimizes for that case.
This is a breaking commit for libzfs! Callers of zfs_get_prop are now
required to initialize src. To preserve existing behavior, they should
initialize it to ZPROP_SRC_NONE.

As soon as wait4() returns, fork() can immediately return with the same
PID, and race to lock _launched_processes_lock, then try to add the new

By locking before wait4(), we ensure, that, given that same
unfortunate scheduling, _launched_processes_lock cannot be locked by the
spawner before we pop the process in the reaper, and only afterward will
it be added
This moves where the reaper idles when there are children from the
wait4() to the pause(), locking for the duration of that single syscall
in both the no-children and running-children cases; the impact of this
is one to two syscalls (depending on _launched_processes_lock state)
