These patches improve ext4's shutdown handling. Most of the problems
that show up when running generic/388 with a single CPU have been
addressed. (There are still problems when running with 2 or more
CPU's.)
Theodore Ts'o (7):
ext4: add tracepoints for shutdown and file system errors
jbd2: clarify bad journal block checksum message
ext4: shutdown should not prevent get_write_access
ext4: eliminate sleep from shutdown ioctl
ext4: pass -ESHUTDOWN code to jbd2 layer
jbd2: if the journal is aborted then don't allow update of the log
tail
ext4: don't update checksum of new initialized bitmaps
