Sorry for the compilation issue.
mmap_read_lock was intrdouced in the following commit.

mmap locking API: initial implementation as rwsem wrappersThe following two commits replaced the usage of mmap_sem rwsem calls with mmap_lock.
d8ed45c5dcd4 (mmap locking API: use coccinelle to convert mmap_sem rwsem call sites) 89154dd5313f (mmap locking API: convert mmap_sem call sites missed by coccinelle)
The first commit is not present in stale 5.7-y for obvious reasons.
Do we need to send a separate patch only for stable branch with mmap_sem ? I am not sure if that will cause a conflict again in future.
I do not like taking odd backports, and would rather take the real patch that is upstream.
I will drop this patch from the tree now, so everyone can figure out what they want to do in the future :)
thanks,
