According to some embodiments, a method in a wireless device comprises obtaining a set of information bits for wireless transmission and dividing the set of information bits into one or more subsets of information bits. For each subset, generating extra cyclic redundancy check (CRC) bits using a CRC polynomial capable of generating N CRC bits. The extra CRC bits for each subset comprise less than N CRC bits. The method further comprises: generating a final set of N or less CRC bits for the set of information bits using the CRC polynomial; generating a set of coded bits by encoding the set of information bits for wireless transmission, together with the extra CRC bits and the final set of CRC bits, using a polar encoder; and transmitting the set of coded bits using a wireless transmitter.

Incremental inline journaling in a journaled file system can be utilized to facilitate concurrency and throughput of a journaled file system. In an example, a request can be received for a transaction to modify a sub-block portion of a file stored in a distributed storage system. In response to that, the modification can be allocated to a data structure in a journal of the distributed storage system. After the transaction commits, a current value of the sub-block portion of the file can be saved to the delta structure. Then, a new value corresponding to the request for the transaction to modify the sub-block portion of the file can be written to the metadata block. After writing the new value to the metadata block, a memory space used to store the delta structure can be freed.
