    Subject[PATCH 11/21] fs: Mark functions as static in jbd2/journal.c
    Mark functions as static in jbd2/journal.c because they are not used
    outside this file.

    This eliminates the following warning in jbd2/journal.c:
    fs/jbd2/journal.c:125:5: warning: no previous prototype for ‘jbd2_verify_csum_type’ [-Wmissing-prototypes]
    fs/jbd2/journal.c:146:5: warning: no previous prototype for ‘jbd2_superblock_csum_verify’ [-Wmissing-prototypes]
    fs/jbd2/journal.c:154:6: warning: no previous prototype for ‘jbd2_superblock_csum_set’ [-Wmissing-prototypes]
