From 868941b14441282ba08761b770fc6cad69d5bdb7 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Wed, 29 Jun 2022 15:07:00 +0200 Subject: fs: remove no_llseek Now that all callers of ->llseek are going through vfs_llseek(), we don't gain anything by keeping no_llseek around. Nothing actually calls it and setting ->llseek to no_lseek is completely equivalent to leaving it NULL. Longer term (== by the end of merge window) we want to remove all such intializations. To simplify the merge window this commit does *not* touch initializers - it only defines no_llseek as NULL (and simplifies the tests on file opening). At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\/d' $i done would do it. Signed-off-by: Jason A.
