stable inclusion from stable-v5.10.145 commit 72602bc62013fa1a41dc931aeed34e78c63fd2e7 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0VF
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 0066f1b0e27556381402db3ff31f85d2a2265858 ]
When trying to get a file lock on an AFS file, the server may return UAEAGAIN to indicate that the lock is already held. This is currently translated by the default path to -EREMOTEIO.
Translate it instead to -EAGAIN so that we know we can retry it.
