| |
Hi!
While testing nilfs2 (using 2.6.30) doing some "cp"s and "rm"s, I noticed sometimes they got stucked in D state, and the kernel had said the following message:
NILFS: IO error writing segment
A friend gave me a hand and after adding some printk()s we found out that the problem seems to occur when bio_alloc()s inside nilfs_alloc_seg_bio() fail, making it return NULL; but we don't know how that causes the processes to get stucked.
PS: Please CC me.
