The open_cnt check is an open-coded D_ASSERT() check. In case the data.work queue is not empty, it does not really help to know which drbd_work elements remained on that list: they will be freed immediately afterwards, anyway. Signed-off-by:

We do not do collision detection for read requests, but we still need to look up the request objects when we receive a package over the network. Using the same data structure for read and write requests results in simpler code once the tl_hash and app_reads_hash tables are removed. Signed-off-by:

Automatic partition scanning can be requested individually per loop device during its setup by setting LO_FLAGS_PARTSCAN. By default, no partition tables are scanned. Userspace can now always add and remove partitions from all loop devices, regardless if the in-kernel partition scanner is enabled or not. The needed partition minor numbers are allocated from the extended minors space, the main loop device numbers will continue to match the loop minors, regardless of the number of partitions used. # grep . /sys/class/block/loop1/loop/* /sys/block/loop1/loop/autoclear:0 /sys/block/loop1/loop/backing_file:/home/kay/data/stuff/part.img /sys/block/loop1/loop/offset:0 /sys/block/loop1/loop/partscan:1 /sys/block/loop1/loop/sizelimit:0 # ls -l /dev/loop* brw-rw---- 1 root disk 7, 0 Aug 14 20:22 /dev/loop0 brw-rw---- 1 root disk 7, 1 Aug 14 20:23 /dev/loop1 brw-rw---- 1 root disk 259, 0 Aug 14 20:23 /dev/loop1p1 brw-rw---- 1 root disk 259, 1 Aug 14 20:23 /dev/loop1p2 brw-rw---- 1 root disk 7, 99 Aug 14 20:23 /dev/loop99 brw-rw---- 1 root disk 259, 2 Aug 14 20:23 /dev/loop99p1 brw-rw---- 1 root disk 259, 3 Aug 14 20:23 /dev/loop99p2 crw------T 1 root root 10, 237 Aug 14 20:22 /dev/loop-control Cc: Karel Zak <kzak@redhat.com> Cc: Davidlohr Bueso <dave@gnu.org> Acked-By:

There are cases where suppressing partition scan is useful - e.g. for lo devices and pseudo SATA devices which advertise to be a disk but get upset on partition scan (some port multiplier control devices show such behavior). This patch adds GENHD_FL_NO_PART_SCAN which suppresses partition scan regardless of the number of possible partitions. disk_partitionable() is renamed to disk_part_scan_enabled() as suppressing partition scan doesn't imply the device can't be partitioned using BLKPG_ADD/DEL_PARTITION calls from userland. show_partition() now directly tests disk_max_parts() to maintain backward-compatibility. -v2: Updated to make it clear that only partition scan is suppressed not partitioning itself as suggested by Kay Sievers.

This commit adds discard support for loop devices. Discard is usually supported by SSD and thinly provisioned devices as a method for reclaiming unused space. This is no different than trying to reclaim back space which is not used by the file system on the image, but it still occupies space on the host file system. We can do the reclamation on file system which does support hole punching. So when discard request gets to the loop driver we can translate that to punch a hole to the underlying file, hence reclaim the free space. This is very useful for trimming down the size of the image to only what is really used by the file system on that image. Fstrim may be used for that purpose. It has been tested on ext4, xfs and btrfs with the image file systems ext4, ext3, xfs and btrfs. ext4, or ext6 image on ext4 file system has some problems but it seems that ext4 punch hole implementation is somewhat flawed and it is unrelated to this commit. Also this is a very good method of validating file systems punch hole implementation. Note that when encryption is used, discard support is disabled, because using it might leak some information useful for possible attacker. Signed-off-by:
