2009-10-25libext2fs: clean up ext2fs_bg_flags_ interfacesEric Sandeen1-1/+1
The ext2fs_bg_flag* functions were confusing. Currently we have this: void ext2fs_bg_flags_set(ext2_filsys fs, dgrp_t group, __u16 bg_flags); void ext2fs_bg_flags_clear(ext2_filsys fs, dgrp_t group,__u16 bg_flags); (_set (unused) sets exactly bg_flags; _clear clears all and ignores bg_flags) and these, which can twiddle individual bits in bg_flags: void ext2fs_bg_flag_set(ext2_filsys fs, dgrp_t group, __u16 bg_flag); void ext2fs_bg_flag_clear(ext2_filsys fs, dgrp_t group, __u16 bg_flag); A better interface, after the patch below, is just: ext2fs_bg_flags_zap(fs, group) /* zeros bg_flags */ ext2fs_bg_flags_set(fs, group, flags) /* adds flags to bg_flags */ ext2fs_bg_flags_clear(fs, group, flags) /* clears flags in bg_flags */ and remove the original ext2fs_bg_flags_set / ext2fs_bg_flags_clear.

2009-07-27e4defrag: remove a lot of cruftEric Sandeen1-81/+34
e4defrag.c had a lot of stuff copied into it from other places, redefinitions of existing interfaces, etc. We should be able to remove most of this, as the tool only works on recent kernels anyway, we should just pick up definitions from recent kernel headers whenever possible. I've left the local definitions of fallocate, fadvise (changed to posix_fadvise) and sync_file_range, and wrapped them in #ifdef configure-time tests - though really it seems like only fallocate should be necessary by now, and perhaps the others can be dropped. We still need some Makefile work so that it won't try to build e4defrag if the right pieces aren't there (and if the local definitions won't work...)

2009-07-02filefrag: fix fm_start in filefrag_fiemap loopPeng Tao1-2/+2
When used with -v and the targeted file has more than 144 extents(double of the length of fm_extents array provided by buf), filefrag_fiemap loops and calls fiemap ioctl() multiple times to calculate the actual number of extents in a file. Each call to fiemap ioctl() uses fm_start as the starting logical offset. The patch fixes fm_start in each loop( except for the first one) and makes the extent calculation correct for files with more that 144 extents. To produce the problem, first run filefrag -v on a highly fragmented file. Then change the buf size in filefrag_fiemap to make it large enough to have all the extent mapped in a single loop and run filefrag -v after recompiling. The former will produce a much smaller extent count because of the false fm_start used in the loop. And the two will produce different extent output since the 145th extent.

2009-07-02Add support for configure --enable-verbose-makecmdsTheodore Ts'o1-151/+151
Some people don't want to see the concise "kernel-style" make output. This configure option allows build engines that want to see the full set of commands executed by the makefile to get what they want. Most people will find this more distracting than useful, unless they need to debug the Makefiles. (It is not necessary to rerun configure to enable this verbose make output temprarily; if a developer wants to do a quick debug of a directory's makefile, he or she can simply edit the definition of the $(E) and $(Q) variables in the Makefile; instructions can be found in the MCONFIG file which is included in at the beginning of every Makefile.)

2009-07-01Fix Makefile dependencies for libcom_errTheodore Ts'o1-6/+7
The e2fsprogs makefiles were using the same Makefile variable LIBCOM_ERR for the link-line arguments as well as the dependencies. Since LIBCOM_ERR can now include non-file arguments such as "-lpthread", we need to use a separate DEPLIBCOM_ERR variable that only has build file dependencies. Do the same thing for STATIC_LIBCOM_ERR and PROFILED_LIBCOM_ERR. Addresses-Sourceforge-Patches: #2813809 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
