Subject: [PATCH 30/30] tests: t3000-resize-fs.sh: Add very deep directory
|
||
|
|
|
||
|
|
Create 500 deep directory tree, with longest name of 4000 characters, to
|
||
|
|
the file system being resized to test the fix to prevent crash when
|
||
|
|
resizing a FAT file system with such a long path.
