# Merge: c71f8fb4dc91 be2ca3825372
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag '9p-for-6.12-rc5' of https://github.com/martinetd/linux
#     
#     Pull more 9p reverts from Dominique Martinet:
#      "Revert patches causing inode collision problems.
#     
#       The code simplification introduced significant regressions on servers
#       that do not remap inode numbers when exporting multiple underlying
#       filesystems with colliding inodes. See the top-most revert (commit
#       be2ca3825372) for details.
#     
#       This problem had been ignored for too long and the reverts will also
#       head to stable (6.9+).
#     
#       I'm confident this set of patches gets us back to previous behaviour
#       (another related patch had already been reverted back in April and
#       we're almost back to square 1, and the rest didn't touch inode
#       lifecycle)"
