The pie.lds.S.in needs two minor changes to work with the gold (/usr/bin/gold) linker. These changes are compatible with /usr/bin/ld and make linker script more portable. The first change is adding a comma before /DISCARD/ so that the grammar won't be ambiguous. A Otherwise, gold treats it as a part of the assignment and would generate a syntax error about the "unexpected ':'". The second change is moving initialization of __export_parasite_args to inside the SECTIONS command because it references the dot symbol. Otherwise, gold would generate the error "invalid reference to dot symbol outside of SECTIONS clause. Signed-off-by:

when decide that data is no longer needed, there are two cases: -if data neighbours previous block of "no needed" data, extend bunch block(it holds begining and size of concequent "no needed" data) by length of curent block and go next. -if data not neighbours bunch block(or bunch block size will be bigger than MAX_BUNCH_SIZE), than we punch bunch block and set bunch block to curent block. in the end make cleanup to punch last bunch block. changes in v1: punch_hole takes whole page_read make restriction more precise Signed-off-by:

No need to check opts.use_page_server, because in write_pagemap_loc write is local anyway. it appeared that on page-server when saving pages to images opts.use_page_server=true and no auto-dedup started, so images were not null as expected. Signed-off-by:

The s_dev value we see in irmap is get from proc file and is raw kernel dev_t. We compare this value to the device get from stat syscall, which is old-style dev_t (with less bits for minor). Thus, need to convert kernel dev_t to stat's dev_t for proper comparison. Signed-off-by: -

When migrating container with copying its FS, the inode numbers and thus their handles wil change. This will make the restore of inotify/fanotify fail, since they do it via fhandles. We've already faced the problems with fsnotifies on NFS -- they don't work there. To address this an irmap cache is created on pre-dump, so to resolve the issue with changed inodes during migration, we can force the irmap cache build. Signed-off-by: -

We are using tar for resting tmpfs. Currently we execute tar from a restored root, but nobody guarantees that it is there and that it's really tar. We don't have reason to change root too early. Lets live in a source root as long as we can, because we can be sure that it's consistent. https://bugzilla.openvz.org/show_bug.cgi?id=2870 v2: remove redundant chdir() Signed-off-by:
