Hello,
I would like to ask about xfs_trans_dup function in
XFS code.
Code comment says,
"This is called to create a new transaction which will
share the permanent log reservation of the given
transaction."
but its explanation is insufficient for me.
when, where can i use this function? what is the role
of xfs_trans_dup function?
please, explain easily and concretly.
In addition,
Is is possible that multiple transactions in XFS code
run like 1 transaction idea(all or nothing)? If
possible, give me the way.
thank you.
