man pagelet’s have a look on man page of file system.

man 5 filesystems

you can find in the file /proc/filesystems which filesystems your kernelcurrently supports.

Before attaching pendrive:



After attaching pendrive

Conclusion :The directory /proc/filesystems does not give the list of file systemswhich my kernel supports.

It gives the list of filesystems which are currently running.



Another wayLet’s check another way:

cat /lib/modules/$(uname -r)/kernel/fs

Conclusion :- /lib/modules/$(uname -r)/kernel/fs will only help withfilesystems that have been enabled as modules, not ones that are builtinto the kernel.

Additionally a module name might not match the filesystem name itprovides, and a single module can provide multiple filesystems.

Solution

--- cat /boot/config ---

--- # # DOS/FAT/NT Filesystems # CONFIG_FAT_FS=m CONFIG_MSDOS_FS=m CONFIG_VFAT_FS=m CONFIG_FAT_DEFAULT_CODEPAGE=437 CONFIG_FAT_DEFAULT_IOCHARSET="utf8" CONFIG_NTFS_FS=m # CONFIG_NTFS_DEBUG is not set



# CONFIG_NTFS_DEBUG is not set CONFIG_NTFS_RW=y # ---

cont…here, m indicated that it is compiled as a module but currently notinserted in kernel

y indicates that it is currently inserted in kernel

We can check the config file which was loaded during the bootingprocess.
