Hey Linus,
/* Summary */
A few years ago struct file_lock_context was added to allow for separate
lists to track different types of file locks instead of using a
singly-linked list for all of them.
Now leases no longer need to be tracked using struct file_lock. However,
a lot of the infrastructure is identical for leases and locks so
separating them isn't trivial.
This pull request splits a group of fields used by both file locks and
leases into a new struct file_lock_core. The new core struct is embedded
in struct file_lock. Coccinelle was used to convert a lot of the callers
to deal with the move, with the remaining 25% or so converted by hand.
Afterwards several internal functions in fs/locks.c are made to work
with struct file_lock_core. Ultimately this allows to split struct
file_lock into struct file_lock and struct file_lease. The file lease
APIs are then converted to take struct file_lease.
/* Testing */
clang: Debian clang version 16.0.6 (19)
gcc: (Debian 13.2.0-7) 13.2.0
All patches are based on v6.8-rc1 and have been sitting in linux-next.
No build failures or warnings were observed.
