MAX_ATTRVAL_SIZE provides a per-filesystem maximum xattr value length
limit. There are a few problems with the current values:
- XFS, UDF and Btrfs are incorrectly hardcoded to use 64 bytes
+ This is a regression from the larger value used prior to fff4359d
+ Btrfs's should be calculated using nodesize and xattr name length
- NFS currently uses a 64K limit
+ This may be above the server's underlying failsystem limit, so use
a conservative estimate instead
The changes are split into four patches to ease review, but feel free
to squash as deemed necessary.
Changes since v2:
- move _attr_get_max() helper into generic/020 and use test-local
$max_attrs / $max_attrval_size variables
- minor commit message changes
