To avoid repeating detection of fssum presence in many btrfs tests, as suggested by Dave Chinner. Also exported the variable "here" from the main control script, to avoid repeating its declaration in every single testcase file. Also removed the declaration of "here" from btrfs test cases that require the fssum program only. Removing it from all other test cases will be a separate change.

# Regression test for a btrfs incremental send issue related to renaming of
|
|
# directories. If at the time of the initial send we have a directory that is
|
|
# a child of a directory with a higher inode number, and then later after the
|
|
# initial full send we rename both the child and parent directories, but
|
|
# without moving any of them, a subsequent incremental send would produce a
|
|
# rename instruction for the child directory that pointed to an invalid path.
|
|
# This made the btrfs receive operation fail.
|
|
#
|
|
# This issue is fixed by the following linux kernel btrfs patch:
|
|
#
|
|
# Btrfs: incremental send, fix invalid path after dir rename
