Subject: [GIT PULL] bcachefs fixes for 6.14-rc1

Hi Linus, just some small stuff.

users seeing specific (reproducable) performance issues should ping me,
I have some new tools for tracking those down

The following changes since commit ff0b7ed607e779f0e109f7f24388e0ce07af2ebe:

  bcachefs: Fix check_inode_hash_info_matches_root() (2025-01-15 15:28:23 -0500)

  bcachefs: Improve trace_move_extent_finish (2025-01-26 23:02:28 -0500)

----------------------------------------------------------------
bcachefs fixes for 6.14-rc1

- second half of a fix for a bug that'd been causing oopses on
  filesystems using snapshots with memory pressure (key cache fills for
  snaphots btrees are tricky)
- build fix for strange compiler configurations that double stack frame
  size
- "journal stuck timeout" now takes into account device latency: this
  fixes some spurious warnings, and the main remaining source of SRCU
  lock hold time warnings (I'm no longer seeing this in my CI, so any
  users still seeing this should definitely ping me)
- fix for slow/hanging unmounts (" Improve journal pin flushing")
- some more tracepoint fixes/improvements, to chase down the "rebalance
  isn't making progress" issues

----------------------------------------------------------------
