Hi all,
I am observing periodic crashes with signature below on kernel 4.4.26.
wb is extracted from page (see mm/page-writeback.c, void
account_page_dirtied() ):
inode_attach_wb(inode, page);
wb = inode_to_wb(inode);
We are crasing in
__inc_wb_stat(wb,
adlocked too in case
the data isn't cached.
It looks scary. I hope that I've missed something.
Best regards,
Angel

The complete backtraces could be found in the attached log.
Do you have any ideas ?
Any help will be greatly appreciated.
