1. A method comprising: initiating, by a first input/output (I/O) scheduling entity executed by a processing device of a computer system, a first process issuing a first I/O operation to an I/O scheduler of the computer system; issuing, by the first I/O scheduling entity, a commitment function to the I/O scheduler, the commitment function to commit the first I/O operation of the first process to a storage device of the computer system, wherein the first process is dependent on completion of a second process comprising a second I/O operation by a second I/O scheduling entity before the commitment function can commit a transaction comprising the first I/O operation to the storage device; issuing, by the first I/O scheduling entity as part of the commitment function, a yield call to the I/O scheduler, wherein a yield component of the I/O scheduler triggers the issuing of the yield call by the first I/O scheduling entity as part of the commitment function in view of the dependency of the first process on the second process; relinquishing, by the first I/O scheduling entity in response to the issuing of the yield call, resources of the I/O scheduler that are used by the first I/O scheduling entity to perform the first I/O operation, the resources of the I/O scheduler relinquished in order to yield the I/O scheduler to the second I/O scheduling entity, wherein the second I/O scheduling entity to initiate, in response to the yielding of the I/O scheduler, the second process that issues the second I/O operation to the I/O scheduler using the relinquished resources of the I/O scheduler from the first I/O scheduling entity in order to complete the transaction; and subsequent to the completion of the transaction, committing, by the I/O scheduler, the transaction to the storage device; wherein the resources comprise processor time or bandwidth for the I/O scheduler assigned to the first I/O scheduling entity to perform the first I/O operation.
