bcachefs: Make sure to go rw if lazy in fsck The paths where we delete or truncate inodes don't pass commit flags for BTREE_INSERT_LAZY_RW, so just go rw if necessary in the fsck code.

bcachefs: Debug mode for c->writes references This adds a debug mode where we split up the c->writes refcount into distinct refcounts for every codepath that takes a reference, and adds sysfs code to print the value of each ref. This will make it easier to debug shutdown hangs due to refcount leaks. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

bcachefs: Fix unmount path There was a long standing race in the mount/unmount code - the VFS intends for mount/unmount synchronizatino to be handled by the list of superblocks, but we were still holding devices open after tearing down our superblock in the unmount path.
