Name:de_peek_iversion_raw - grab a "raw" iversion value*@inode: inode from which i_version should be read* Grab a "raw" inode->i_version value and return it. The i_version is not* flagged or converted in any way. This is mostly used to access a self-managed

| Name | Describe |
|---|---|
| inode_set_max_iversion_raw | de_set_max_iversion_raw - update i_version new value is larger*@inode: inode to set*@val: new i_version to set* Some self-managed filesystems (e.g Ceph) will only update the i_version* value if the new value is larger than the one we already have. |
| inode_maybe_inc_iversion | de_maybe_inc_iversion - increments i_version*@inode: inode with the i_version that should be updated*@force: increment the counter even if it's not necessary?* Every time the inode is modified, the i_version field must be seen to have |
| inode_iversion_need_inc | de_iversion_need_inc - is the i_version in need of being incremented?*@inode: inode to check* Returns whether the inode->i_version counter needs incrementing on the next* change. Just fetch the value and check the QUERIED flag. |
| inode_peek_iversion | de_peek_iversion - read i_version without flagging it to be incremented*@inode: inode from which i_version should be read* Read the inode i_version counter for an inode without registering it as a* query |
| inode_query_iversion | de_query_iversion - read i_version for later use*@inode: inode from which i_version should be read* Read the inode i_version counter |
| inode_eq_iversion_raw | de_eq_iversion_raw - check whether the raw i_version counter has changed*@inode: inode to check*@old: old value to check against its i_version* Compare the current raw i_version counter with a previous one. Returns true |
