  - drm/xe: Fix shrinker accounting double-subtraction on nested external pins xe_bo_pin_external() and
    xe_bo_unpin_external() support nested pins, since the underlying ttm_bo_pin()/ttm_bo_unpin() maintain a
    pin_count refcount rather than a boolean. However, the shrinker accounting calls
    xe_ttm_tt_account_subtract() and xe_ttm_tt_account_add() are invoked unconditionally on every
    pin_external()/unpin_external() call, instead of only on the transition into and out of the pinned state.
    An external BO (dma-buf) can be pinned more than once while already pinned, for example when it has
    multiple attachments/importers, each independently calling xe_bo_pin_external(). Each such nested pin
    subtracts the BO's pages from the shrinker's accounting again, even though the BO's pages were already
    removed from consideration by the first pin. Symmetrically, each nested unpin adds them back again before
    the BO is actually unpinned. This desynchronizes the shrinker's page and object counts from reality, and
    since they are declared as signed long but interpreted as unsigned long in xe_shrinker_count(), the
    underflow can turn into an enormous shrinkable/purgeable page count, causing the shrinker to be invoked
    excessively under memory pressure. Guard the accounting calls with the same pin-count transition checks
    already used to guard the pinned_link list maintenance, so accounting is only updated on the outermost pin
    and the final unpin. While centralizing this logic into xe_bo_account_pin()/ xe_bo_account_unpin(), also
    close a second, related accounting gap affecting imported dma-bufs. For an imported bo's ttm_tt, xe's
    ttm_tt_populate hook (xe_ttm_tt_populate()) early-returns without calling xe_ttm_tt_account_add(), since
    TTM_TT_FLAG_EXTERNAL is set without TTM_TT_FLAG_EXTERNAL_MAPPABLE. However, TTM core's ttm_tt_populate()
    wrapper unconditionally marks the tt as populated on driver-hook success, so ttm_tt_is_populated() still
    reports true for it. xe_bo_account_pin()/xe_bo_account_unpin() trusted ttm_tt_is_populated() as a proxy
    for these pages are accounted for by the shrinker, and would subtract/add pages for such a tt that were
    never added in the first place, again underflowing the shrinker's counts. This is reachable today via
    xe_bo_pin_external(), and would have become newly reachable via the fb-pin path once this patch routes
    __xe_pin_fb_vma() through xe_bo_pin_account() below, so fix it here rather than in a later patch, to avoid
    a commit in this series that introduces the regression before fixing it. Skip the accounting for imported
    bos, using the same EXTERNAL && !EXTERNAL_MAPPABLE test xe_ttm_tt_populate()/xe_ttm_tt_unpopulate() use to
    decide whether to act, via a new xe_ttm_bo_is_imported() helper (hoisted up from its only prior use site).
    v2: - Fix the critical issue caught by Sashiko AI review: the pin-count transition check introduced here
    was still bypassed by the fb-pin path (__xe_pin_fb_vma()/__xe_unpin_fb_vma()), which could leave a stale
    pinned_link entry and a permanent shrinker accounting leak when the fb-unpin performed the true last
    unpin. Addressed in a separate follow-up patch in this series rather than folded in here, since it is a
    distinct bug with its own Fixes: tag. - Drop the unneeded local last_unpin variable in
    xe_bo_unpin_external(), restoring the original inline bo->ttm.pin_count == 1 check; it was a no-op rename
    not used by any of the new accounting helpers, and was going to be deleted again by the follow-up patch
    anyway. v3: - Exclude imported dma-bufs from the pin/unpin shrinker accounting, fixing another underflow
    caught by Sashiko AI review. - Add a short comment on the backup-object pin site noting it's already
    populated/accounted at pin time, addressing (as a false-positive clarification, no code fix needed) a
    separate Medium-severity accounting-leak concern also caught by Sashiko AI ---truncated---
