Currently, a linear scan of the inode blocks is required to fetch the next free inode. Possibly add another field at the end of an inode ssize_t i_next_free_inum and use it to form a linked list of sorts like the freelist. Addition and removal to be done from the head. This ensures O(1) fetch.

Can use either of:
sendmail
mailx

• Check how to print debug / fprintf / printf logs in FUSE client
• Run a simple linux command on write handler in FUSE and print output

Currently, the filesystem size and the disk storage device path are hardcoded in header/disk_layer.h. We should add a shell script that compiles the filesystem with relevant flags to define the disk path and filesystem size during compilation and mounts it on the given disk path.

The same needs to be done for mkaltfs.

Understanding is required on where FUSE handles permissions and where the filesystem needs to do that. The interface layer must be updated accordingly and tests added for the same.

Simply intercept system calls and output in console

The fuse_file_information struct is almost a copy of the stat struct. It should be able to hold the inode number for a file descriptor once opened and function as an inode cache for us. The cache size can be reduced if this becomes possible.
