[Deepin-Kernel-SIG] [linux 6.6.y] [Upstream] Sync xfs code clean from v6.17-rc1

[opsiff]

Summary by Sourcery

Clean up and streamline XFS tracepoints to match upstream, including config-guarding compat ioctl traces and dropping unused or obsolete events.

Enhancements:

• Guard the XFS compat ioctl inode tracepoint with CONFIG_COMPAT to align with configuration options.
• Remove unused or obsolete XFS trace events related to direct write completion, page cache invalidation, allocation, attribute handling, reflink operations, copy-on-write ENOSPC handling, log I/O, and attribute state returns to reduce tracepoint noise and maintenance overhead.

Reviewer's Guide

This PR syncs XFS tracepoint definitions in xfs_trace.h with upstream by dropping unused or removed trace events and guarding a compat-only inode trace event with CONFIG_COMPAT, keeping the trace set aligned with current kernel behavior.

Hey - I've left some high level feedback:

• After removing these trace events, double-check that there are no remaining references (e.g., tracepoints names in debug helpers, scripts, or tracepoint class reuse) that would now cause build or runtime issues.
• For the new CONFIG_COMPAT guard around xfs_file_compat_ioctl, verify that the declaration and any call sites are consistently guarded in the same way to avoid mismatched symbol availability in different build configurations.
