Instead of passing a fmode_t and only checking it fo0r FMODE_WRITE, pass a bool open_for_write to prepare for callers that won't have the fmode_t. Signed-off-by:

There is no real need to store the open mode in the super_block now. It is only used by f2fs, which can easily recalculate it. Signed-off-by:

Add a helper to return the open flags for blkdev_get_by* for passed in super block flags instead of open coding the logic in many places. Signed-off-by:

The current interface for exclusive opens is rather confusing as it requires both the FMODE_EXCL flag and a holder. Remove the need to pass FMODE_EXCL and just key off the exclusive open off a non-NULL holder. For blkdev_put this requires adding the holder argument, which provides better debug checking that only the holder actually releases the hold, but at the same time allows removing the now superfluous mode argument.

Passing a holder to blkdev_get_by_path when FMODE_EXCL isn't set doesn't make sense, so pass NULL instead and remove the holder argument from the call chains the only end up in non-FMODE_EXCL blkdev_get_by_path calls. Exclusive mode for device scanning is not used since commit 50d281fc ("btrfs: scan device in non-exclusive mode")". Signed-off-by:

sb is just an on-stack pointer that can easily be reused by other calls. Switch to use the bcache-wide bcache_kobj instead as there is no need to claim per-bcache device anyway. Signed-off-by:

Set a flag when a cdrom_device_info is opened for writing, instead of trying to figure out this at release time. This will allow to eventually remove the mode argument to the ->release block_device_operation as nothing but the CDROM drivers uses that argument. Signed-off-by:

For whole devices ->open is called for each open, but for partitions it is only called on the first open of a partition, e.g.: open("/dev/vdb", ...) open("/dev/vdb", ...) - 2 call to ->open open("/dev/vdb1", ...) open("/dev/vdb", ...) - 2 call to ->open open("/dev/vdb", ...) open("/dev/vdb", ...) - just open call to ->open This is problematic as various block drivers look at open flags and might not do all the required setup if the earlier open was with an odd flag like O_NDELAY or the magic 3 ioctl-only open mode.
