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.

# FS QA Test No. btrfs/030

|
# Regression test for btrfs' incremental send feature:
|
|
#
|
|
# 1) Create several nested directories;
|
|
# 2) Create a read only snapshot;
|
|
# 3) Change the parentship of some of the deepest directories in a reverse
|
|
# way, so that parents become children and children become parents;
|
|
# 4) Create another read only snapshot and use it for an incremental send
|
|
# relative to the first snapshot.
|
|
#
|
|
# At step 4 btrfs' send entered an infinite loop, increasing the memory it
|
|
# used while building path strings until a krealloc was unable to allocate
|
|
# more memory, which caused a warning dump in dmesg.
