From 1e1fd567d32fcf7544c6e09e0e5bc6c650da6e23 Mon Sep 17 00:00:00 2001 From: Mikulas Patocka mpatocka@redhat.com Date: Tue, 13 Aug 2024 12:38:51 +0200 Subject: [PATCH] dm suspend: return -ERESTARTSYS instead of -EINTR
This commit changes device mapper, so that it returns -ERESTARTSYS instead of -EINTR when it is interrupted by a signal (so that the ioctl can be restarted).
The manpage signal(7) says that the ioctl function should be restarted if the signal was handled with SA_RESTART.
