[so2] [Tema 5] Problema pitix_write_inode

Buna,

Am o problema atunci cand creez un director sau un fisier nou; acestea sunt
create,
apar in output-ul comenzii ls -l, dar dupa rularea comenzii  primesc un
"NULL pointer
dereference" din functia pitix_write_inode.

Am folosit addr2line ca sa vad linia care genereaza eroarea si arata ca ar
fi de la
"if (!bh)", unde bh e buffer head-ul obtinut dupa citirea unui block de
inodes, dar nu derefrentiez nimic in instructiunea respectiva.

Are cineva vreo idee care ar putea fi problema?

Multumesc,
Diana
