# commit e01a83e12604aa2f8d4ab359ec44e341a2248b4a
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Mon Jan 22 15:39:01 2024 -0800

#     Revert "btrfs: zstd: fix and simplify the inline extent decompression"
#     
#     This reverts commit 1e7f6def8b2370ecefb54b3c8f390ff894b0c51b.
#     
#     It causes my machine to not even boot, and Klara Modin reports that the
#     cause is that small zstd-compressed files return garbage when read.
