This is done through recently # added helpers. # # - Fix a page leak if write_begin() fails. # # - Fix afs_write_begin() to not alter the dirty region info stored in # page->private, but rather do this in afs_write_end() instead when we # know what we actually changed. # # - Fix afs_invalidatepage() to alter the dirty region info on a page # when partial page invalidation occurs so that we don't inadvertantly # include a span of zeros that will get written back if a page gets # laundered due to a remote 3rd-party induced invalidation. # # We mustn't, however, reduce the dirty region if the page has been # seen to be mapped (ie. we got called through the page_mkwrite vector) # as the page might still be mapped and we might lose data if the file # is extended again. # # - Fix the dirty region info to have a lower resolution if the size of # the page is too large for this to be encoded (e.g. powerpc32 with 64K # pages). # # Note that this might not be the ideal way to handle this, since it # may allow some leakage of undirtied zero bytes to the server's copy # in the case of a 3rd-party conflict. # # To aid the last two fixes, two additional changes: # # - Wrap the manipulations of the dirty region info stored in # page->private into helper functions. # # - Alter the encoding of the dirty region so that the region bounds can # be stored with one fewer bit, making a bit available for the # indication of mappedness. # # * tag 'afs-fixes-20201029' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: # afs: Fix dirty-region encoding on ppc32 with 64K pages # afs: Fix afs_invalidatepage to adjust the dirty region #
