Question $12$

Given a FILESYSTEM of type VSFS studied in the lecture, which uses a block size of $4096$ bytes. In FILESYSTEM there is a single file named foo$/,$ size $4096$ bytes. A process writes a string of $11$ bytes to the offset $($OFFSET$)4090$ in the file as follows:

int fd $=$ open$("/$foo$",$ O$\_$RDWR$)$; lseek$($fd$,4090,$ SEEK$\_$SET$)$; write$($fd$,$ "hello world", $11)$;

Assume that the process is the only one that accesses SYSTEM CALLS FILESYSTEM do not fail and the write$()$ writes the entire string; And there is no CACHING of blocks from the disk in the memory $($in particular, a change of the block in the FILESYSTEM causes the block to be written to the disk$).$

How many operations will $10$ result in executing the plan?

S $911$ d$.$
