If anyone has any objections, please let me know. ------------------ From: Josef Bacik [ Upstream commit 0185c2292c600993199bc6b1f342ad47a9e8c678 ] In our user safe ino resolve ioctl we'll just turn any ret into -EACCES from inode_permission(). This is redundant, and could potentially be wrong if we had an ENOMEM in the security layer or some such other error, so simply return the actual return value. Note: The patch was taken from v5 of fscrypt patchset (https://lore.kernel.org/linux-btrfs/cover.1706116485.git.josef@toxicpanda.com/) which was handled over time by various people: Omar Sandoval, Sweet Tea Dorminy, Josef Bacik.
