Kernel: Fix directory permissions
...
We did not care about X bit in directories and instead used only the
R bit for search/read.

Kernel: Fix bug in disk writing
...
I have used two weeks in locating a bug in my ext2 implementation
while the bug was actually in disk write. If you called write_sectors
on disk it would write the first sector_size bytes repeatedly to all
asked sectors and this corrupted the disk...

Use getchar() instead of fread(&ch, 1, sizeof(char), stdin). This

flawed. It should not return on '\n'
