Revision 1d151c337d79fa3de88654d2514f58fbd916a8e0 authored by Cyrill Gorcunov on 30 July 2012, 21:43:00 UTC, committed by Linus Torvalds on 31 July 2012, 00:25:21 UTC
When we restore file descriptors we would like them to look exactly as they were at dumping time. With help of fcntl it's almost possible, the missing snippet is file owners UIDs. To be able to read their values the F_GETOWNER_UIDS is introduced. This option is valid iif CONFIG_CHECKPOINT_RESTORE is turned on, otherwise returning -EINVAL.
