Linux FAT File Creation/Birth Time Reporting, Proposal For Statx I/O Alignment Info
First up, queued into Andrew Morton's patch queue is creation time reporting for FAT file-systems. This is for proper file creation/birth time handling for FAT16/FAT32 file-systems on Linux. The Linux driver has reported a creation time "ctime" previously but ultimately muddled as the change time for a file as well.
With this patch expected to be merged for the upcoming Linux 5.19 cycle, FAT creation time is properly reported via statx now just like the creation/birth time reporting for the various other file-systems added in the years since this system call was introduced.
Separately, Google's Eric Biggers has proposed extending statx to be able to report I/O alignment information. The statx reporting for I/O alignment can be used by user-space for determining when a file supports direct I/O and the involved alignment details. This also allows ensuring user-space uses proper I/O alignment for a file. His "RFC" patch series adds the I/O alignment information to statx and wires it up for EXT4 and F2FS file-systems.
