Subject: [PATCH] toolcontext: fix double free (core dumped) issue
How to trigger:
```
~ # export LVM_SYSTEM_DIR=_
~ # pvscan
No matching physical volumes found
double free or corruption (!prev)
Aborted (core dumped)
```
when LVM_SYSTEM_DIR is empty, _load_config_file() won't be called.
when LVM_SYSTEM_DIR is not empty, cfl->cft links into cmd->config_files
by _load_config_file()@lib/commands/toolcontext.c
core dumped code: _destroy_config()@lib/commands/toolcontext.c
```
/* CONFIG_FILE/CONFIG_MERGED_FILES */
if ((cft = remove_config_tree_by_source(cmd, CONFIG_MERGED_FILES)))
config_destroy(cft);
else if ((cft = remove_config_tree_by_source(cmd, CONFIG_FILE)))
config_destroy(cft); <=== first free the cft
dm_list_iterate_items(cfl, &cmd->config_files)
config_destroy(cfl->cft); <=== double free the cft
```

Subject: [PATCH 1/3] fsadm: add support to resize & check btrfs filesystem
To: lvm-devel@redhat.com,
zkabelac@redhat.com,
teigland@redhat.com
Check: mount the device first and then run`btrfs filesystem scrub start
-B` command
Reisze: find the mount point first and resize the filesystem after get
the device id since there are maybe several devices underneath btrfs
resize:
btrfs volume may spanning across multiple block devices. resize action should
specific subvolume to not to break the filesystem on LV about to get resized
with lvresize.
this patch finds the mount point first and resizes the filesystem after
getting the device id since there are maybe several devices underneath btrfs
filesystem

by heming.zhao@suse.com 2021.6.8
modify patch according to upstream code
check:
check the data integrity.
this patch mounts the device first and then runs `btrfs filesystem scrub
start -B` command
