nilfs2: remove nilfs_cpfile_{get,put}_checkpoint()

2024-02-22T23:38:53+00:00

All calls to nilfs_cpfile_get_checkpoint() and
nilfs_cpfile_put_checkpoint() that call kmap() and kunmap() separately are
now gone, so remove these methods.

nilfs2: localize highmem mapping for checkpoint reading within cpfile

2024-02-22T23:38:53+00:00

Move the code for reading from a checkpoint entry that is performed in
nilfs_attach_checkpoint() to the cpfile side, and make the page mapping
local and temporary.  And use kmap_local instead of kmap to access the
checkpoint entry page.

In order to load the ifile inode information included in the checkpoint
entry within the inode lock section of nilfs_ifile_read(), the newly added
checkpoint reading method nilfs_cpfile_read_checkpoint() is called
indirectly via nilfs_ifile_read() instead of from
nilfs_attach_checkpoint().

nilfs2: localize highmem mapping for checkpoint finalization within cpfile

2024-02-22T23:38:53+00:00

Move the checkpoint finalization routine to the cpfile side, and make the
page mapping local and temporary.  And use kmap_local instead of kmap to
access the checkpoint entry page when finalizing a checkpoint.

In this conversion, some of the information on the checkpoint entry being
rewritten is passed through the arguments of the newly added method
nilfs_cpfile_finalize_checkpoint().

nilfs2: localize highmem mapping for checkpoint creation within cpfile

2024-02-22T23:38:53+00:00

In order to convert kmap() used in cpfile to kmap_local, first move the
checkpoint creation routine, which is one of the places where kmap is
used, to the cpfile side and make the page mapping local and temporary. 
And use kmap_local instead of kmap to access the checkpoint entry page
(and header block page) when generating a checkpoint.

nilfs2: convert to SPDX license tags

2018-09-04T23:45:02+00:00

Remove the verbose license text from NILFS2 files and replace them with
SPDX tags.  This does not change the license of any of the code.

nilfs2: move ioctl interface and disk layout to uapi separately

2016-08-02T23:35:21+00:00

The header file "include/linux/nilfs2_fs.h" is composed of parts for
ioctl and disk format, and both are intended to be shared with user
space programs.

This moves them to the uapi directory "include/uapi/linux" splitting the
file to "nilfs2_api.h" and "nilfs2_ondisk.h".  The following minor
changes are accompanied by this migration:

 - nilfs_direct_node struct in nilfs2/direct.h is converged to
   nilfs2_ondisk.h because it's an on-disk structure.
 - inline functions nilfs_rec_len_from_disk() and
   nilfs_rec_len_to_disk() are moved to nilfs2/dir.c.

This removes the extra paragraph which mentions FSF address in GPL

related to it.
