Hi David,
If no maintainer else sees it and comments, i'm going to send a new
patch, only keep btrfs part and withdraw rest, and take care of sashiko
comments as well.
Please still find it, many thanks.
Best regards,
Song

This patchset adds fault injection support for btrfs_data_csum_ok,
enabling controlled simulation of checksum mismatches to test btrfs
silent data corruption detection and reporting paths.
The first patch extends the error injection framework with a new type,
EI_ETYPE_FALSE, which allows bool-returning functions to be overridden
with a false return value directly.
The second patch marks btrfs_data_csum_ok with ALLOW_ERROR_INJECTION
using this new type.
The third patch adds a parent field to fei_attr to allow fault injection
on a function only when called from a specific parent function.
Song Chen (3):
error-injection: Introduce EI_ETYPE_FALSE for fail_function
btrfs: Allow error injection on btrfs_data_csum_ok
error-injection: Introduce parent in fei_attr
I'm going through my mailbox and found this. No objections to add the
injection point to btrfs, but the rest is generic fault injection code
so I can't take it via btrfs tree without acks.
There are some sashiko comments (as replies in the thread [1]) and there
have been some changes to btrfs code too so the patchset needs a
refresh.
I see maintainers in CC, if somebody could please let us know how to
proceed.
