15 : /* A note on fd_borrowed_account_acquire_write:
16 :
17 : The stake program uses this function to prevent aliasing of accounts.
18 : (When the same account is passed via multiple instruction account
19 : indexes.) Internally, it acquires a transaction-wide mutex on the
20 : account. If called twice on the same account while the mutex is
21 : still locked, it returns an "AccountBorrowFailed" error.
22 :
23 : There is no exact equivalent to this in Agave/Rust.
24 :
25 : let handle = instruction_context.try_borrow_instruction_account(...)
26 :
27 : The above creates the lock on the account. However, that lock is
28 : **implicitly** released when 'handle' goes out of scope. Firedancer
29 : releases the handle **explicitly**. */
