# FS QA Test No. 503
|

|

|
# This is a regression test for kernel patch:
|
||
|
|
# ext4: handle layout changes to pinned DAX mapping
|
||
|
|
#
|
||
|
|
# This test exercises each of the DAX paths in ext4 which remove blocks from
|
||
|
|
# an inode's block map. This includes things like hole punch, truncate down,
|
||
|
|
# etc. This test was written to regression test errors seen with an ext4 +
|
||
|
|
# DAX setup, but the test runs fine with or without DAX and with XFS so we
|
||
|
|
# don't require the DAX mount option or a specific filesystem for the test.
