Abstract
Techniques for a managing concurrent I/Os in a file system may include receiving a sequence of conflicting I/O lists of write data stored in a cache, the sequence specifying a sequential order in which the I/O lists are to be flushed to a file stored on non-volatile storage; determining a first I/O list of the sequence having a conflict with a second I/O list of the sequence, wherein the conflict between the first I/O list and the second I/O list is a first common block written to by both the first and second I/O lists; and performing first processing that modifies the first I/O list and the second I/O list to remove the conflict.
