+ <mcsim> Why for big buffers in ext2fs used own allocator, that just
+ allocates many pages at once, instead of using malloc?
+ <mcsim> i.e. can I replace it with malloc, because it just complicates
+ things?
+ <braunr> mcsim: probably because of alignment
+ <braunr> what gets complicated by that ?
+ <mcsim> braunr: than valloc?
+ <mcsim> braunr: this allocator allows to allocate only buffer with size of
+ vm_page_size.
+ <mcsim> valloc just would be clearer.
+ <braunr> valloc ?
+ <braunr> valloc is obsolete
+ <mcsim> braunr: than memalign or posix_memalign?
+ <mcsim> memalign obsolete too... would posix_memalign be eligible?
+ <braunr> mcsim: why memalign instead of the custom allocator ?
+ <mcsim> because, I think, it is clearer. Also, since I need to allocate any
+ amount of pages, not just one, I have to edit custom allocator. Although
+ it is not hard, but using ready stuff seems more sane for me.
+ <mcsim> braunr: ^
+ <braunr> right, but make sure posix_memalign doesn't create too much
+ overhead
+ <mcsim> braunr: what kind of overhead?
+ <braunr> fragmentation
+ <braunr> i assume the glibc implementation is careful about that, but still

+ <infinity0> ah thanks i'll look that up
