What is FILE_COMPLETE_IF_OPLOCKED

NTFSD
1

FILE_COMPLETE_IF_OPLOCKED in IFS doc:
Complete this operation immediately with an alternate success code “if the
target file is
oplocked”, rather than blocking the caller’s thread.

now how to find “if the target file is oplocked”?

If the file is oplocked, the thread that called may need to execute an
APC to process the oplock break on the file. Since you’ve probably
blocked APCs (FsRtlEnterFileSystem) this can’t happen so you need to
return a special code so the caller can execute the APC and finish the
oplock break.

If that’s the case, when you call FsRtlCheckOplock it will return an
appropriate status code (STATUS_OPLOCK_BREAK_IN_PROGRESS).
