check_fsid() provides a method to verify if the given device is mounted with the tempfsid in the kernel. Function sb() is an internal only function. Signed-off-by: Anand Jain <anand.jain@oracle.com> --- v2: Drop the function sb() Use $AWK_PROG instead of awk. egrep -> grep -E common/btrfs | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+)
