Relocate the memory allocation for ttc table after the switch statement
that validates params->ns_type in both mlx5_create_inner_ttc_table() and
mlx5_create_ttc_table(). This ensures memory is only allocated after
confirming valid input, eliminating potential memory leaks when invalid
ns_type cases occur.

Currently, sdp->sd_aspace and the per-inode metadata address spaces use
sb->s_bdev->bd_mapping->host as their ->host; folios in those address
spaces will thus appear to be on bdev rather than on gfs2 filesystems.
This is a problem because gfs2 doesn't support cgroup writeback
(SB_I_CGROUPWB), but bdev does.
Fix that by using a "dummy" gfs2 inode as ->host in those address
spaces. When coming from a folio, folio->mapping->host->i_sb will then
be a gfs2 super block and the SB_I_CGROUPWB flag will not be set in
sb->s_iflags.
Based on a previous version from Bob Peterson from several years ago.

this out.

it does violate the DLM API. Fix that by only setting DLM_LKF_VALBLK
when sb_lvbptr is not NULL.

Previously, copygc and rebalance weren't started until the very end of
mounting, after all recvoery passes have finished.
But copygc really should be started earlier, since it may be needed for
allocations to make forward progress. Additionally, we've been seeing
occasional bug reports where starting the kthread fails due to a pending
signal - i.e. we're getting timed out by systemd (during a version
upgrade), but we're not seeing the signal until mount is about to
complete.
Additionally, we now have copygc/rebalance explicitly wait for
check_snapshots to complete (if being run); they require that for
snapshot_is_ancestor() in the data move path.

According to CXL r3.2 section 8.2.1.2, the PCI_COMMAND register fields,
including Memory Space Enable bit, have no effect on the behavior of an
RCD Upstream Port. Retaining this check may incorrectly cause
cxl_pci_probe() to fail on a valid RCD upstream Port.
While the specification is explicit only for RCD Upstream Ports, this
check is solely for accessing the RCRB, which is always mapped through
memory space. Therefore, its safe to remove the check entirely. In
practice, firmware reliably enables the Memory Space Enable bit for
RCH Downstream Ports and no failures have been observed.
Removing the check simplifies the code and avoids unnecessary
special-casing, while relying on BIOS/firmware to configure devices
correctly. Moreover, any failures due to inaccessible RCRB regions
will still be caught either in __rcrb_to_component() or while
parsing the component register block.
The following failure was observed in dmesg when the check was present:
cxl_pci 0000:7f:00.0: No component registers (-6)
