Subject: [PATCH 168/198] xfs: Convert inode numbers to cpu endianity
|
|
|
23d2ea |
immediately after reading
|
|
|
ecb9bb |
|
|
|
ecb9bb |
Currently XFS driver converted inode numbers to native endianity only
|
|
|
ecb9bb |
when using them to compute inode position. Although this works, it is
|
|
|
ecb9bb |
somewhat confusing. So convert inode numbers when reading them from disk
|
|
|
ecb9bb |
structures as every other field.
