* xfs: streamline defer op type handlingDarrick J. Wong2018-12-121-1/+0
| | | | | | | | | | There's no need to bundle a pointer to the defer op type into the defer op control structure. Instead, store the defer op type enum, which enables us to shorten some of the lines.

* xfs: idiotproof defer op type configurationDarrick J. Wong2018-12-121-8/+2
| | | | | | | | | | | | Recently, we forgot to port a new defer op type to xfsprogs, which caused us some userspace pain. Reorganize the way we make libxfs clients supply defer op type information so that all type information has to be provided at build time instead of risky runtime dynamic configuration.

* xfs: drop dop param from xfs_defer_op_type ->finish_item() callbackBrian Foster2018-08-021-1/+0
| | | | | | | | | | | | The dfops infrastructure ->finish_item() callback passes the transaction and dfops as separate parameters. Since dfops is always part of a transaction, the latter parameter is no longer necessary. Remove it from the various callbacks.

* xfs: convert to SPDX license tagsDave Chinner2018-06-061-15/+1

This does not change the license of any of the code, merely refers to the common, up-to-date license files in LICENSES/ This change was mostly scripted. fs/xfs/Makefile and fs/xfs/libxfs/xfs_fs.h were modified by hand, the rest were detected and modified by the following command: for f in `git grep -l "GNU General" fs/xfs/` ; do echo $f cat $f | awk -f hdr.awk > $f.new mv -f $f.new $f done And the hdr.awk script that did the modification (including detecting the difference between GPL-2.0 and GPL-2.0+ licenses) is as follows: $ cat hdr.awk BEGIN { hdr = 1.0 tag = "GPL-2.0" str = "" } /^ \* This program is free software/ { hdr = 2.0; next } /any later version./ { tag = "GPL-2.0+" next } /^ \*\// { if (hdr > 0.0) { print "// SPDX-License-Identifier: " tag print str print $0 str="" hdr = 0.0 next } print $0 next } /^ \* / { if (hdr > 1.0) next if (hdr > 0.0) { if (str != "") str = str "\n" str = str $0 next } print $0 next } /^ \*/ { if (hdr > 0.0) next print $0 next } // { if (hdr > 0.0) { if (str != "") str = str "\n" str = str $0 next } print $0 } END { } $ Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.

* xfs: get rid of the log item descriptorDave Chinner2018-05-101-2/+2
| | | | | | | | | | | | | | | | | | It's just a connector between a transaction and a log item. There's a 1:1 relationship between a log item descriptor and a log item, and a 1:1 relationship between a log item descriptor and a transaction. Both relationships are created and terminated at the same time, so why do we even have the descriptor? Replace it with a specific list_head in the log item and a new log item dirtied flag to replace the XFS_LID_DIRTY flag.

* xfs: remove double-underscore integer typesDarrick J. Wong2017-06-191-1/+1
| | | | | | | | | | | | | | | | | | | | This is a purely mechanical patch that removes the private __{u,}int{8,16,32,64}_t typedefs in favor of using the system {u,}int{8,16,32,64}_t typedefs. This is the sed script used to perform the transformation and fix the resulting whitespace and indentation errors: s/typedef\t__uint8_t/typedef __uint8_t\t/g s/typedef\t__uint/typedef __uint/g s/typedef\t__int\([0-9]*\)_t/typedef int\1_t\t/g s/__uint8_t\t/__uint8_t\t\t/g s/__uint/uint/g s/__int\([0-9]*\)_t\t/__int\1_t\t\t/g s/__int/int/g /^typedef.*int[0-9]*_t;$/d Signed-off-by: Darrick J.

* xfs: propagate bmap updates to rmapbtDarrick J. Wong2016-08-031-4/+9
| | | | | | | | | | | | | | | | | | | | | | When we map, unmap, or convert an extent in a file's data or attr fork, schedule a respective update in the rmapbt. Previous versions of this patch required a 1:1 correspondence between bmap and rmap, but this is no longer true as we now have ability to make interval queries against the rmapbt. We use the deferred operations code to handle redo operations atomically and deadlock free. This plumbs in all five rmap actions (map, unmap, convert extent, alloc, free); we'll use the first three now for file data, and reflink will want the last two. We also add an error injection site to test log recovery. Finally, we need to fix the bmap shift extent code to adjust the rmaps correctly. Signed-off-by: Darrick J.
