This is a note to let you know that I've just added the patch titled dm suspend: return -ERESTARTSYS instead of -EINTR to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: dm-suspend-return-erestartsys-instead-of-eintr.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit a2c5f5755e7b168b3abff9676a708ccc2b48a940 Author: Mikulas Patocka <mpatocka@xxxxxxxxxx> Date: Tue Aug 13 12:38:51 2024 +0200 dm suspend: return -ERESTARTSYS instead of -EINTR [ Upstream commit 1e1fd567d32fcf7544c6e09e0e5bc6c650da6e23 ] 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.
