The bot has tested the following trees: v5.5.11, v5.4.27, v4.19.112, v4.14.174, v4.9.217, v4.4.217.

v5.5.11: Build OK!
v5.4.27: Build OK!
v4.19.112: Failed to apply! Possible dependencies:

v4.14.174: Failed to apply! Possible dependencies:
1863d77f15da ("SUNRPC: Replace the cache_detail->hash_lock with a regular spinlock")

v4.9.217: Failed to apply! Possible dependencies:

NOTE: The patch will not be queued to stable trees until it is upstream.

How should we proceed with this patch?
