zfs: support force exporting pools
This is primarily of use when a pool has lost its disk, while the user doesn't care about any pending (or otherwise) transactions. Implement various control methods to make this feasible: - txg_wait can now take a NOSUSPEND flag, in which case the caller will be alerted if their txg can't be committed. This is primarily of interest for callers that would normally pass TXG_WAIT, but don't want to wait if the pool becomes suspended, which allows unwinding in some cases, specifically when one is attempting a non-forced export. Without this, the non-forced export would preclude a forced export by virtue of holding the namespace lock indefinitely. - txg_wait also returns failure for TXG_WAIT users if a pool is actually being force exported. Adjust most callers to tolerate this. - spa_config_enter_flags now takes a NOSUSPEND flag to the same effect. - DMU objset initiator which may be set on an objset being forcibly exported / unmounted. - SPA export initiator may be set on a pool being forcibly exported. - DMU send/recv now use an interruption mechanism which relies on the SPA export initiator being able to enumerate datasets and closing any send/recv streams, causing their EINTR paths to be invoked. - ZIO now has a cancel entry point, which tells all suspended zios to fail, and which suppresses the failures for non-CANFAIL users. - metaslab, etc. cleanup, which consists of simply throwing away any changes that were not able to be synced out. - Linux specific: introduce a new tunable, zfs_forced_export_unmount_enabled, which allows the filesystem to remain in a modified 'unmounted' state upon exiting zpl_umount_begin, to achieve parity with FreeBSD and illumos, which have VFS-level support for yanking filesystems out from under users. However, this only helps when the user is actively performing I/O, while not sitting on the filesystem. In particular, this allows test #3 below to pass on Linux. - Add basic logic to zpool to indicate a force-exporting pool, instead of crashing due to lack of config, etc. Add tests which cover the basic use cases: - Force export while a send is in progress - Force export while a recv is in progress - Force export while POSIX I/O is in progress This change modifies the libzfs ABI: - New ZPOOL_STATUS_FORCE_EXPORTING zpool_status_t enum value. - New field libzfs_force_export for libzfs_handle.

# DESCRIPTION:
|
||||
# A pool should be force exportable, while a send is running from it.
|
||||
#
|
||||
# STRATEGY:
|
||||
# 1. Initiate a send from pool to a file.
|
||||
# 2. Slow the send using pv, so it blocks a normal pool export.
|
||||
# 3. Check that normal export fails.
|
||||
# 4. Forcibly export pool.
|
||||
# 5. Verify pool is no longer present in the list output.
