Wengang Wang 5040f8df56 ocfs2: free up write context when direct IO failed ... The write context should also be freed even when direct IO failed. Otherwise a memory leak is introduced and entries remain in oi->ip_unwritten_list causing the following BUG later in unlink path: ERROR: bug expression: !list_empty(&oi->ip_unwritten_list) ERROR: Clear inode of 215043, inode has unwritten extents ... Call Trace: ? __set_current_blocked+0x42/0x68 ocfs2_evict_inode+0x91/0x6a0 [ocfs2] ? bit_waitqueue+0x40/0x33 evict+0xdb/0x1af iput+0x1a2/0x1f7 do_unlinkat+0x194/0x28f SyS_unlinkat+0x1b/0x2f do_syscall_64+0x79/0x1ae entry_SYSCALL_64_after_hwframe+0x151/0x0 This patch also logs, with frequency limit, direct IO failures.
