Hi, I was doing some testing on a 4.18-rc1 kernel, and a single threaded test wrote a fairly large file to a XFS file system, causing it to fill up. After that the process hung in D state for a long time, and only recovered after several minutes. Here's the backtrace during the hang: [<0>] wb_wait_for_completion+0x5e/0x90 [<0>] sync_inodes_sb+0xc9/0x290 [<0>] xfs_flush_inodes+0x25/0x30 [xfs] [<0>] xfs_file_buffered_aio_write+0x2be/0x300 [xfs] [<0>] __vfs_write+0x114/0x1a0 [<0>] vfs_write+0xad/0x1a0 [<0>] ksys_write+0x52/0xc0 [<0>] do_syscall_64+0x5b/0x160 [<0>] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [<0>] 0xffffffffffffffff There were no IO errors or similar. Expected? Already fixed?
