Patch series “zram: fix zram issues reported by sashiko”.<\/p>\n
Sashiko drove by and reported [1] a couple of zram issues:
\na possible BUG_ON() in zlib code due to missing winbits range
\nvalidation and one possible NULL-ptr dereference in zcomp.
\nBoth are low risk yet still worth fixing.<\/p>\n
This patch (of 2):<\/p>\n
zram_destroy_comps() resets all compressors and leaves them set to NULL,
\nincluding the primary one, which is invalid device state, as now
\ncomp_algorithm_show()->strcmp() can be called on a NULL compressor. Set
\ndefault primary compressor in zram_destroy_comps().<\/p>\n","protected":false},"excerpt":{"rendered":"
