Subject: [PATCH 0/2] Couple of efivarfs fixes
Date: Thu, 28 May 2020 12:49:03 -0700 [thread overview]
Message-ID: <20200528194905.690-1-tony.luck@intel.com> (raw)
1) Some apps want to monitor changes in EFI variables, but reading the
file and comparing is inefficient. Just have Linnux update the
modification time when a file is written
2) A rate limited read can return -EINTR ... very suprising to apps.
Tony Luck (2):
efivarfs: Update inode modification time for successful writes
efivarfs: Don't return -EINTR when rate-limiting reads
