Subject: [PATCH 412/506] xfs: Convert inode numbers to cpu endianity
|
|
immediately after reading
|
|
|
|
Currently XFS driver converted inode numbers to native endianity only
|
|
when using them to compute inode position. Although this works, it is
|
|
somewhat confusing. So convert inode numbers when reading them from disk
|
|
structures as every other field.
