[pso] [tema 2 ] linux - deadlock ciudat

[octavian ganea]

Am si eu o problema ciudata:

In functia read am urmatoarele linii:

printk(LOG_LEVEL "5 :am intrat in READ; size_read=%d\n",  data->size_read );

    spin_lock_irqsave(&data->lock_read, flags);

    printk(LOG_LEVEL "6 !!!!!!!!!com %d :am intrat in READ; size =%d; unde
offset=%d, size_read=%d; x=%d\n", com, size, *offset, data->size_read, x );

De fiecare data cand rulez, pe la primele teste se blocheaza (inclusiv
masina virtuala) pentru ca : msjul 5 afiseaza un data->size_read (dim
bufferului de read) corect , dar msjul 6 afiseaza data->size_read= 0 ; intre
aceste doua printk-uri nu imi intra in intrerupere . Ce poate sa il
determine sa reseteze size_read ?

Multumesc
