+Subject: [PATCH] fix(mksquashfs): use st_atimespec on macOS
+
+Darwin struct stat does not expose st_atim. Use st_atimespec on macOS while keeping existing behavior on other platforms.

-Subject: [PATCH] mksquashfs: don't create duplicate virtual -> real disk
- mappings
-
-This bug is caused by commit 472588dc40292fa3d047369f1e758016a6b26e70,
-but it is exposed by commit 078529915caab11e85299aac1304671151d507a3.
-
-The first commit adds a virtual -> real disk mapping in cases where a
-multi-block file contains all sparse blocks.   In this case no data
-block has been written for this file, and it may mean no virtual -> real
-disk mapping will exist otherwise.
-
-However, a side effect of this is two duplicate virtual -> real disk
-mappings may be created, with different values.
-
-Now previously before commit 078529915caab11e85299aac1304671151d507a3,
-Mksquashfs waited for all outstanding data blocks to be processed by the
-orderer thread before creating the metadata.  At this point all the
-duplicate virtual -> real disk mappings will exist, and the lookup
-routine will return the last one created - which happens to be the
-correct one.
-
-After commit  078529915caab11e85299aac1304671151d507a3, Mksquashfs no
-longer waits for all outstanding data blocks to be processed by the
-orderer thread, which means when the lookup takes place in metadata
-creation, there may exist only the first wrong duplicate, which will be
-returned.  Obviously there may exist both duplicate values in which case
-the correct one will be returned.   In other words this is a race
-condition,  and it is highly dependent on hardware and input data
-whether it triggers.
-
-The fix is to increment the virtual disk position after creating a
-mapping when a multi-block file contains all sparse blocks.  This
-obviously prevents duplicate mappings from being created.
-
-Fixes https://github.com/plougher/squashfs-tools/issues/339
