# FS QA Test No. btrfs/053

|
|
# Verify that btrfs send is able to replicate xattrs larger than PATH_MAX.
|
|
# This is possible if the b+tree leaf size is larger than 4Kb (mkfs.btrfs's
|
|
# default is max(16Kb, PAGE_SIZE) as of btrfs-progs v3.12, and max(4Kb,
|
|
# PAGE_SIZE in older versions).
|
|
#
|
|
# This issue is fixed by the following linux kernel btrfs patch:
|
|
#
|
|
# Btrfs: send, use the right limits for xattr names and values
