19 hourscmd_list_journal: new optionsHEADmasterKent Overstreet
-D, --datetime Print out one line per journal entry, with datetime it was written -L, --log-only Only print entries containing log messages -F, --flush-only Only print flush commits Additionally, we now print a line for missing journal entry ranges. These make it easier to get an overall picture of what happened in the journal - in particular, seeing how far back we can rewind before we have gaps.

6 dayscmd_fsck: Online fsck can now specify a mountpointKent Overstreet
If the specified path is a directory, we'll try to run online fsck on the filesystem mounted at that path. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
11 dayscmd_image_createKent Overstreet
Add a tool for creating small image files. Data is written out in a reproducible order, sequentially from the start of the device. Metadata is initially written to a temporary device, then after writing out data, the metadata we want to keep (alloc info is left out by default) is migrated to the real device. Then, the image file is trimmed to minimum size and the temporary metadata device dropped. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
11 dayscmd_strip_allocKent Overstreet
Add a command for stripping allocation info for a filesystem. This is primarily to test codepaths used by the new image creation tool. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2025-05-25Fix infinite loop in cmd_list_journalKent Overstreet
list_journal can print the entire contents of the journal, and non-dirty entries don't get validated, so we have to account for that. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21cmd_dump: Don't use noexcl by defaultKent Overstreet

It was forcing human readable units even without the -h flag, so use the functions that respect that configuration.

2025-04-29Don't use xclose() in splice_fd_to_stdinout()Kent Overstreet
The splice fd might have been closed, and a double-close here shouldn't be a concern because we're not doing any interesting multithreaded things and it's local to this function. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Add an option for controlling whether we create a third redundant superblock at the end of the device. For image files that are going to immediately be resized, we want to skip this. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
