NFSD: Enforce timeout on layout recall and integrate lease manager fencing
When a layout conflict triggers a recall, enforcing a timeout is
necessary to prevent excessive nfsd threads from being blocked in
__break_lease ensuring the server continues servicing incoming
requests efficiently.
This patch introduces a new function to lease_manager_operations:
lm_breaker_timedout: Invoked when a lease recall times out and is
about to be disposed of. This function enables the lease manager
to inform the caller whether the file_lease should remain on the
flc_list or be disposed of.
For the NFSD lease manager, this function now handles layout recall
timeouts. If the layout type supports fencing and the client has not
been fenced, a fence operation is triggered to prevent the client
from accessing the block device.
While the fencing operation is in progress, the conflicting file_lease
remains on the flc_list until fencing is complete. This guarantees
that no other clients can access the file, and the client with
exclusive access is properly blocked before disposal.
