-Subject: [PATCH] multi: make sure 'data' can present in several sockhash
- entries
-
-Since more than one socket can be used by each transfer at a given time,
-each sockhash entry how has its own hash table with transfers using that
-socket.
-
-In addition, the sockhash entry can now be marked 'blocked = TRUE'"
-which then makes the delete function just set 'removed = TRUE' instead
-of removing it "for real", as a way to not rip out the carpet under the
-feet of a parent function that iterates over the transfers of that same
-sockhash entry.
-
-Reported-by: Tom van der Woerdt
-Fixes #3961
-Fixes #3986
-Fixes #3995
-Fixes #4004
-Closes #3997

+Subject: [PATCH] multi: make sure 'data' can present in several sockhash
+ entries
+
+Since more than one socket can be used by each transfer at a given time,
+each sockhash entry how has its own hash table with transfers using that
+socket.
+
+In addition, the sockhash entry can now be marked 'blocked = TRUE'"
+which then makes the delete function just set 'removed = TRUE' instead
+of removing it "for real", as a way to not rip out the carpet under the
+feet of a parent function that iterates over the transfers of that same
+sockhash entry.
+
+Reported-by: Tom van der Woerdt
+Fixes #3961
+Fixes #3986
+Fixes #3995
+Fixes #4004
+Closes #3997
