If static_key_false( & crct10dif_fallback) Then Return crc_t10dif_generic(crc, buffer, len)

_read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other

tfm = fetch RCU-protected pointer for dereferencing(crct10dif_tfm)

ctx = crc

72

err = rypto_shash_update() - add data to message digest for processing*@desc: operational state handle that is already initialized*@data: input data to be added to the message digest*@len: length of the input data

73

_read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
