This makes it clear when we are using "mount ; umount" versus "mount
-o remount" for most file systems. The reason for this distinction is
(a) tests may want to test the difference between what happens on the
remount versus the munt paths, (b) with tmpfs, "mount ; umount" will
cause the contents of all of the files to disappear which makes many
tests sad, and (c) some mount options may not be changed using "mount
-o remount".
Currently _scratch_mount performs "_scratch_mount ; _scratch_umount"
so mechnically rename this function to _scratch_cycle_mount. This was
done mechnically using the script fragment:
git grep "_scratch_remount" | \
awk -F: '{print $1}' | sort -u | \
xargs sed -i 's/_scratch_remount/_scratch_cycle_mount/g'

# Test inline_data behaviors when filesystem is full.
|
|
#
|
|
# The inline_data feature was introduced in ext4 and f2fs as follows.
|
|
# ext4 : http://lwn.net/Articles/468678/
|
|
# f2fs : http://lwn.net/Articles/573408/
|
|
#
|
|
# The basic idea is embedding small-sized file's data into relatively large
|
|
# inode space.
|
|
# In ext4, up to 132 bytes of data can be stored in 256 bytes-sized inode.
|
|
# In f2fs, up to 3.4KB of data can be embedded into 4KB-sized inode block.
