[PATCH 1/4] xfsdump: remove conditional OPENMASKED code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



xfsdump contains a couple wrapper functions which block signals
during an open(2) call. This code is conditionally compiled and has
not been enabled for a long time. Remove the wrappers rather than
converting them to use the POSIX signal API.
