thread_should_wake() in background.c

[Vikram Mehta]

Hi ,

When I mount jffs2 partition

the system simply stops responding
after givinng the message


JFFS2: Garbage collect thread is pid 1792
thread_should_wake(): nr_free_blocks 1, nr_erasing_blocks 15, dirty_size 0x0
jffs2_garbage_collect_thread sleeping...
thread_should_wake(): nr_free_blocks 1, nr_erasing_blocks 15, dirty_size 0x0


thread_should_wake() is in fs/jffs2/background.c

Any ideas Y is this so

with kind regards
Vikram
