Subject: [PATCH 5.14 122/432] f2fs: fix to keep compatibility of fault injection interface

From: Chao Yu <chao@...nel.org>

[ Upstream commit b96d9b3b09f0427b289332c6f6bfbf747a19b654 ]

The value of FAULT_* macros and its description in f2fs.rst became
inconsistent, fix this to keep compatibility of fault injection
interface.
