mkfs: fix to avoid format of device when already mounted
In case of embedded devices, where /etc/ is mounted as 'read-only'.
We donot have the /etc/mtab file. So, checking if the device is already
mounted from this file is not sufficient.
Try to read /proc/mounts in case of failure from /etc/mtab.
Issue logs:
/dev/sdb4 /mnt vfat rw,relatime,fmask=0022,dmask=0022,codepage=cp437,
iocharset=ascii,errors=remount-ro 0 0
Here device - sb4 is already mounted.
But, when trying to format using mkfs.f2fs
F2FS-tools: Ver: 1.1.0 (2013-01-14)
Info: sector size = 512
Info: total sectors = 13108784 (in 512bytes)
WARN: Align start sector number in a unit of pages
i.e., start sector: 2542124, ofs:4 (sectors per page: 8)
Info: zone aligned segment0 blkaddr: 186
Info: This device doesn't support TRIM
Info: format successful
After Change:
F2FS-tools: Ver: 1.1.0 (2013-01-14)
Error: /dev/sdb4 is already mounted
