[PATCH 23/31] mount.nfs: Use correct data type in discover_nfs_mount_data_version()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Address compiler warning:

    mount.c: In function ‘discover_nfs_mount_data_version’:
    mount.c:162: warning: comparison between signed and unsigned
    mount.c:164: warning: comparison between signed and unsigned
    mount.c:166: warning: comparison between signed and unsigned
    mount.c:168: warning: comparison between signed and unsigned
    mount.c:170: warning: comparison between signed and unsigned
    mount.c:178: warning: comparison between signed and unsigned

linux_version_code() and MAKE_VERSION() both return an unsigned int.
