Issue a sync call before doing the initial inode scan so that any inode changes in the inode cache are reflected in the bulk stat calls. This is necessary for incremental dumps to work properly (i.e. not skip files) so that all inodes changed before the dump time are included in the dump.

When using -z, check a file's size against the max dump file size just before dumping the file, rather than only during the initial scan.

The DMF-specific code in xfsdump was taking a shortcut in estimating the dump size of a file in order to avoid the cost of reading the DMF extended attribute. This caused migrating (MIG) files to be identified as dual-state (DUL) files, which lead to an estimated size of 0 for MIG files rather than their true size. In general it's okay for the estimate to be wrong, but there are a couple of cases where the estimate needs to be as accurate as possible, even if it means slowing down the initial inode scan. These cases are 1) multiple dump streams, since the estmated size is used to determine where to split the dump, and 2) when excluding files over a certain size from the dump. Only the second case applies on Linux, since multiple dump streams are not currently supported. This mod changes the DMF-specific code to get an accurate dump size estimate when either of the above cases are in effect.

Change xfsdump to use its inode map to determine the next inode of interest when doing inode scans. This prevents unecessary bulkstat calls when dumping only a fraction of a filesystem, e.g., when doing a subtree or incremental dump.

Improve subtree dump performance. The old way of doing subtree dumps was to scan the entire filesystem and add all inodes to the inomap. The non-selected subtrees were then recursed over and those inos were effectively removed from the inomap. The amount of take this takes if related to the size of the filesystem, not the size of the subtree(s) being dumped. The new way of building the inomap for subtree dumps is to recurse over the selected subtrees and adding each ino to the dump. There's no need to do a full filesystem scan to build the inomap, and no need to scan files that are not in the selected subtree. As a result this tends to be a 5-10x speedup over the old method, depending on the size of the subtree relative to the size of the filesystem.

The inomap was implemented to all efficient lookups in increasing ino order. This doesn't work well for dealing with subtrees, since recursing through subtrees will result in processing inodes in non-increasing ino order. Change the inomap lookup routines to use binary search, and use a cursor to remember where the previous search ended. This allows fast lookups for random lookups, and keeps sequential lookups fast as well.

xfsdump had a set of macros and a set of functions for manipulating the inomap state bits. xfsrestore had a set of macros to do the same, although the macros were different. This mod removes the macros for manipulating inomap state bits and uses the inline functions instead.

This mod adds a number of optimizations to increase the performance of xfsdump and xfsrestore, especially on filesystems with millions of inodes. Many small changes were made to minimize the number of system calls required per inode. Significant changes to xfsdump: - Cache the gen number of each inode during the initial inode scan so that a bulkstat single does not need to be done for each inode when dumping directories. - No longer retrieve the DMF attribute when estimating the dump size of a file. Use information from the bulkstat instead. - Retrieve DMF attribute by handle instead of doing open/attr_getf/close. - In determining where to split multi-stream dumps, take into consideration the number of files and not just the file size. This allows filesystems with large amounts of inodes but relatively little data (DMF filesystem) to be split correctly. Significant changes to xfsrestore: - Buffer writes to the namreg file to eliminate 2 very small write system calls per directory entry. - Buffer writes to dirattr file to eliminate a small write system call per directory. - Speedup the check to see if a particular window of the tree file is mapped. This allows xfsrestore to use more, smaller windows which is beneficial if we can't fit them all in memory and have to start unmapping them. This also makes the -w option obsolete so that option now has no effect. - Change the hash function to give a better distribution among the hash buckets. - Do not make an unnecessary unlink call if the file being restored does not already exist.

Update xfsdump man page to explain how to use chattr to exclude subtrees from a dump. Also deprecate the usage of the SGI_XFSDUMP_SKIP_FILE extended attr as a method for tagging files to be skipped. For now just print a warning if the attribute is found and still skip the file; down the road we can stop checking for the attribute entirely.

Change xfsdump and xfsrestore to unconditionally compile support for extended attributes and DMAPI event flags. Noticed some code which would revert to an old media format if the user requested that extended attributes not be dumped. The intention being to make the dumps compatible with old xfsrestores (really old now). But using the old media format means that holes will not be efficiently encoded in the dump. So I'm removing this code so that we always dump in the current media format.

Add support to properly dump and restore the new inode flags: immutable, append, sync, noatime and nodump. Add all inode flags, new and old, to the list defined in _mk_fillconfig_ea() of cmd/xfstests/common.dump. Test 063 can be used to verify the proper backup and restore of these flags. Also update man pages to 1) remove reference to miniroot (IRIX-only), 2) document the new XFS_XFLAG_NODUMP inode flag as the preferred method to exclude files, and 3) better describe how the media inventory files can be used. The code for the inode flags was contributed by Ethan Benson, with copyright assignment obtained by Nathan Scott. Add code to honour new XFS_XFLAG_NODUMP inode flag. This will becom the 'preferred' method to exclude files. The old-style extended attribute, SGI_XFSDUMP_SKIP_FILE, will still be supported (don't break backward compatibility).
